Even CS technically if you play competitive on faceit, which is still pretty dumb.
There’s plenty that actually work though, even with anticheat: areweanticheatyet.com
Anti cheat preventing gaming on Linux is honestly an outlier at this stage. It just means the devs don’t want to deal with working with an additional OS which several other devs and valve itself has shown is not a major issue anymore. Both EAC and BattleEye have had linux userspace clients for years, and both support WINE now.
Also because they probably can’t convince linux users to install a kernel level anti cheat as if that isn’t rootkit spyware lol. Akmod and dkms devs would probably laugh if Riot tried such a thing.
