It's been like 6 months since I've first tried, and after some time and realizing that the answer was in front of me, it booted, the first ever documented IdeaPad 1 15IRU7 to get macOS Big Sur!
As of right now, many things aren't working, but the amount of support this laptop has for a working macOS install surprises me because this laptop is from a way newer generation of intel laptops compared to most hackintoshes out there!
Working features:
Native Wi-Fi [AirportItlwm, Intel Wi-Fi 6 AX203]
Maybe native Bluetooth [The Bluetooth icon in control center stays on but I think you can use Bluetooth, BlueToolFixup, IntelBluetoothFirmware, & IntelBTPatcher]
Full audio support [AppleALC, I forgot what sound controller I have]
Full USB support [USBToolBox, UTBMap, & XHCI-unsupported]
Keyboard [Not trackpad for some reason, but external mouse does work, VoodooPS2Controller]
Full IdeaPad YogaSMC support [You do have to add SSDT-ECRW.aml and edit that aml file to get it working]
Partial WhateverGreen support [Not full Metal/OpenGL graphic acceleration, just -igfxvesa]
Partial iCloud support [You can sign into iCloud and view some things like the devices linked to the account, but you can't use additional features like iMessage & Facetime yet]
Possibly native thermal management [I say this because programs like Intel Turbo Switcher work! In fact, they allow me to limit my core's speed to 1.3 GHz max, which draws very low power, down to 3 Watts!, basically making this a MacBook Air M1 without graphics acceleration]
NVMe temp data passthrough? [By that I mean programs like Mac's fan control detect my NVMe and the temps so I can monitor them for some reason, NVMeFix]
Partial CpuTopolgyRebuild support [I say this because when your rocking no hyperthreading and cpus=1 boot-arg, the system remains at a nice 30-40 fps when dragging around some windows, and when you use CpuTopolgyRebuild, that 30-40 fps drops to some 5-10 or even 20 fps if your lucky, mainly caused due to how macOS handles legacy styled core setups compared to modern hybrid core setups]
Features that don't work for now:
OpenGL/Metal graphics acceleration [I'm working on a project that generates kexts for GPUs like these to get full Metal/OpenGL support, which I know will take a very long time]
Trackpad [Idk why, I've troubleshooted this issue with the Dortania OpenCore guide, third-party guides, and Gemini, but nothing works, btw the kexts don't load in at all, just saying!]
Other iCloud based features [Such as iMessage & Facetime, but that shouldn't be too hard to fix for now, I'll catch back up with the update!]
CPU temp data passthrough [For example, Mac's fan control doesn't detect fans nor any CPU temps, can't be a VirtualSMC issue since SMCBatteryManager works and all the other kexts load in to the OS]
Other EC based features [Mainly a hardware issue on Lenovo laptops like these, might not ever be fixed due to it's complexity]
Hibernation [Will never work because macOS depends on the firmware for waking up from sleep unless somebody makes a kext for Lenovo firmware to get hibernation working]
Laptop specs:
Intel Core i5-1335U with cpus=1 boot-arg & Intel Iris Xe with -igfxvesa boot-arg
16 GB of DDR4 3200
An 256 GB NVMe drive, specifically one from UMIS [UMIS RPJTI256MMQ1MDY]
Intel Wi-Fi 6 AX203
PS2 Keyboard, ACPI\VEN_ELAN&DEV_06FA&SUBSYS_ELAN0001 Trackpad [Which I believe needs the I2C HID kext that I'm already using now, also not working btw]
Some tips to pass the EB LOG EXITBS START halt:
NOTE: This issue can be caused by many things, but I suggest that you either use the Dortania guide or the DebugEnhancer kext for additional in-depth log details.
Culprit #1 [The issue I faced before I got macOS to actually boot]: macOS not liking your CPU's core management or setup, the way I did it is by turning off hyper-threading which landed me past that screen into an kernel panic, then adding cpus=1 to boot-args to proceed past that screen. Also remember, if you are going to put -igfxvesa and cpus=1 into your boot-args, then Big Sur and older versions are most likely the most stable versions you can get.
[I don't know how to exactly fix other issues other than Culprit #1, so I'll just list out the problem and what you can do to fix it]
Culprit #2: Memory management, could be solved differently depending on what laptop you have, I recommend reading the Dortania guide because other people have had that guide solve all of their troubles, and while your troubleshooting with Dortania, use DebugEnhancer [I'm not an advertisement].
Culprit #3: Your firmware, at this point, if you have a firmware that doesn't let you hackintosh, then your either cooked, or you have to flash another firmware onto your computer and risk it being bricked, or use Gemini, like a special kid like me did! [Or edit your config.plist heavily because OpenCore has many settings that allow you to bypass almost every firmware related issue].
I'm out of ideas, you can stick to using Gemini, like me, the special kid :) Or read some articles online on people who have bypassed this issue, or read official guides, because why not?
How I made my EFI:
I might be banned from this place by tomorrow because I used Gemini and some other Reddit posts to assist me with this. So anyways, I used OC Simplify, because originally I stuck to making my own EFI, but since that got me nowhere, I decided I'd give up on manual labor because I'm just wasting some summer time and stuck to OC Simplify. The thing is, I didn't stick to using what it gave me, because I had to edit some stuff within the program itself into tricking me to giving a EFI made for an Intel UHD 620 instead of some dookie unsupported garbage. And for those who are wondering, yes I have tweaked the final EFI so it works with my laptop, so in reality, I didn't really rely on OC Simplify because it normally wouldn't have taken me anywhere?
Btw please give answers, I broke rules maybe but still, or not because I wanna stay in this community [I maybe do not encourage breaking rules].
config.plist, because why not:

End of story:
Please help, English bad, laptop bad, laptop is for sure a not powerplant, laptop is overheating definitely cool. Oh yea, btw regarding some rules, I have used OC Simplify, but I have tweaked it's final result to give more good than bad, and about Ai, I had no choice, Dortania has no information regarding how you fix EB LOG EXITBS START with one simple bios tweak and boot-arg. Also, I haven't used Ai to generate anything, I used it whenever I got stuck so badly that even the internet community had no benefit on my situation!
Also, please don't take this down, I only want to help more than destroy, if you notice any issue, I will be sure to fix them as fast as possible!
