If it's cheaper for them to pay lawyers a few tens or hundreds of millions to bury any such case in court, in settlements, or putting the agitator through any of the myriad forms of living hell they can legally get away with, then they'll go that route.

You'd need an immensely rich or influential opponent to decide they wanted to march through hell in order to hold Google's feet to the fire. It'd have to be something deeply personal and they probably have things structured to limit any potential liability to a couple hundred million. They'll never be held to account for anything that goes seriously wrong.
