He can demand it because he’s different. Everyone is trying to find the “next tyreek hill” but they can’t because his speed is rare - it’s not just running a fast 40, he’s on a different level with game speed that’s hard to replicate.
I think you go in knowing that he going to do that at least once a game and you just need to move on to the next play. The key is scoring more points and getting to mahomes. There is no “scheme” to stop hill, like there is no “scheme” to stop Josh Allen because of the rare athleticism.
