Any time when a player slips and falls down when another player's hands are on them is a very tough call for the officials (correlation versus causation).
Mahomes asking for the flag on that is ridiculous. Couldn't a DT start to jump sideways and not enter the neutral zone to make the o-line jump offside?
The holding call on VDM when Cook fumbled out of bounds they never showed the reply. From what I could see live, the defender so far upfield by the time Cooks went through the hole that there is no way it had an impact on the play.
