Yesterday was the first day of Nature day, so I went to log on and discovered it was also the day I got K.K. Slider to perform on my island. Leif didn't show up yesterday, and still hasn’t showed up today.
My game is updated, because Redd is on my island, any suggestions?
User discussion of the game online seems to indicate that it does not, or at least that it isn't an especially robust filter:

The tweet in question also has replies featuring others' screenshots of names one would expect a language filter to catch.
There is no problem leaving your switch on sleep. When you come back to the game the next day, it will check your system clock and update the game state accordingly. Cutscenes will start if you have one pending.

For me today was the first day Leif appeared (and the art dealer).
So I guess when KK is in town, any other random appearance in the square is cancelled, and it leaves the space for KK.
So I guess the game skipped your first 'Leif day' and he will appear the next time he would be scheduled to. (I don't know if he is on a schedule or like other 'square vendors' he has a chance to appear every day.)
