The vcrun2015 overrides are the issue.
In a clean 32bit prefix, run winetricks to install vcrun2013 and d3dx9. Then
add a (native, builtin) override for msvcp140 from winecfg. Running
LeagueClient.exe --no-sandbox using the patched wine should now work.

Sometimes it does show unhandled exceptions or
err:ntdll:RtlpWaitForCriticalSection. To fix that, I just kill all the lol
processes, remove the lockfile in lol's installation directory, and try again
until it works. Usually runs fine after 2-3 attempts.
