Those first two are reported to work incredibly well using proton compatibility on steam. Proton is not the same as native support, which is why its not mentioned in any official game Information.

A platinum (community) rating though is as high as it gets, may as well be native or better then on windows.

For TFT i found they use the same anti cheat as some other games. Used to work before, no longer does now but with dual boot all your current stuff is just a minute away (windows updates not included)
