I think they technically could, but won’t, and never have. using ReVanced isn’t nearly as much of a legal problem as Vanced, because ReVanced isn’t directly providing modified versions of the official app (which would be redistributing modified copyrighted material), and even then, only team Vanced themselves suffered the consequences, by being forced to shut down. Modifying whatever for your own personal use doesn’t come with any copyright issues.

Banning people who use ReVanced would be like banning people who use adblockers on desktop. not only it’s not sure if that is actually against their terms of services (they can probably make the argument that ad-less playback is supposed to be a paid feature, and getting it for free is bad), they would never realistically go out of their way to ban everyone who figured out a way to have YouTube without ads. how about browsers with built-in adblockers? how about people who set up adblockers at their router’s level, impacting everyone else connected to it?

it’s never impossible that they do it, but so far it has never happened. no website has ever banned its users for using adblockers; at most, they would display a popup forcing you to disable it to access the site (youtube actually does that, but said popup is just as easily blocked than ads themselves). considering the huge amount of "what if"s, I don’t believe it will ever happen, especially not with no warnings.
