Epic didn’t sue for damages. They sued to get the rules changed. The jury did not award Epic any money. The judge will be deciding how Google must remedy the situation

The judge cannot override the jury's ruling, so unless Google's appeal succeeds, the ruling stays.

Yes, as your own comment points out. Juries determine questions of fact. That can't (for the most part, there are of course exceptions) be revised by a judge. The applied penalty is a very different thing, and can be and usually is revised by the judge.

The jury was only finding guilt, penalty has not happened yet so we don’t know what kind of fines or whatever Google will have to deal with.
