While Kayn does have a higher winrate compared to Illaoi, when they face off with one another, Kayn also has a much greater difficulty level that makes him a more complex character to pick up and master.

Moreover, Kayn also has almost no amount of utility and CC, a similar amount to Illaoi. This often makes her just as valuable during team fights, especially when facing champions with a lot of burst damage.
