There were 2 questionable ref calls, the replay of 3rd down and the non-call on Burrow get roughed. If you're gonna call late hit out of bounds on Mahomes, you have to call roughing on Burrow.
Overall, I didn't see anything that tells me the refs were purposely tilting the table.
As for the NFL office, I don't trust them at all. It is total nonsense for a team to not be able to challenge a spot under 2 minutes, but you can challenge it at any time. A bad spot cost Cincy a timeout at the end of the first half, but KC challenged a spot later and had the call overturned. That's a problem with the NFL office, not the refs.
The Eagles are going to lose. There is no way they beat Mahomes.
