Good AI Overhaul Mod?

Been enjoying SPT way more than I do the base game but I've started to notice the PMCs have a weird facination with my left arm.
From several hundred meters away bots seem to detect what class armor I'm wearing and if they can pen it, they'll aim centre-mass but if they can't, they'll beam my left arm. I always check the after-action screen to see where I was hit and 9 times out of 10 it'll be a clean left-arm/collateral from left-arm kill, no blunt damage or stray rounds anywhere else. I'm a complete noob but I don't think that kind of visual armor detection/penetration calucation and recoil control to place 3/4 shots into an arm a mile away in the span of 2 seconds is possible for a lot of players in tarkov. All I know is playing tarkov you would almost always have armor come back through insurance half damaged, but in SPT it'll barely have a scratch on it unless you died to M995/Igolnik in which it'll be damaged because they'll focus on thorax instead.

Basically just looking for a mod to make the AI more realistic and less cheatsy with their aim or someway to change the settings to make the AI spray a bit more like a normal player and not beam a single limb. Thx in advance.

Edit: Btw I have seen SAIN 2.0 but it didn't seem to mention anything making bot aim more realistic and I'm not really looking for something to make bots harder at the moment until I can fix the aimbot.

Update:
This is the type of thing I mean, I died before I even had time to react, and I died to a thorax kill after the AI calculated it could pen my class 5 armor from a quarter of the map away and not a single shot missed or hit anything else.
