First of all: current triple A game leaks are pretty rare.
And secondly their code base tend to be so complex, they are of little use to most of the people except maybe Chinese/Russian companies.
Besides, publishers will chase you to the hell and back, if you associate with those leaks.
But usually there are attempts to at least get them to compile and run, e.g. GTA5 source that's on rutracker compiles and runs locally.
If you are interested in current games, here's what most people do and what you don't see going around as a "source leaks":
Forget about big budget AAA games and decompile a bunch of smaller games, which were made on engine or framework of your choice
and lift whatever you need from them (menu system/shaders/AI logic/physics/etc)
UE/Unity/Godot/GameMaker/Clickteam Fusion/C#/Python/Lua/Java <-- all of those decompile with generic tools you can find on github
And that's like 80% of what comes out on Steam these days
