That aside, I imagine invidious (app) servers which allow users to watch content from Google's servers may be candidates for shutdown.
For example, here's a random video from the front page of an invidous server about the reddit blackout (I haven't watched it): https://yewtu.be/watch?v=fBruoybHryU
But the video itself is coming from https://rr1---sn-ux3n588t-t8ge.googlevideo.com/
I assume this would be nominally legal under the same reasoning that hotlinking images is legal. If hotlinking images is found to be illegal though (which I think Google is powerful enough to force), then I think Google is going to have to do some reorganizing of their index (see case where someone sued Google, and lost, because Google was prominently displaying a website that hotlinked their image: https://www.theregister.com/2020/01/16/google_search_image_r...)
So it's an interesting one to watch for precedent, but I don't think Google is going to want to force courts to agree that hotlinking another website is infringement, because they'd potentially have to deindex 90% of the internet.
On the other hand, their search result quality has reduced so drastically of late, maybe they don't care about this.
