Why wouldn't they?
1. Already in anti-trust related to ads, AI is probably in the clear.
2. If they are thought to violating a law they will get like a $10,000,000 fine and pay it, still less money than they will make from harvesting data.
Seems like the real issue is that Google is using proceeds from the core illegal monopoly to fund a dumping operation in another market in order to establish a monopoly there. They've been able to dump a free browser on the market and smother any potential competition in that space in the same fashion.

"Already in trouble for committing monopolist behavior in market A, Google should be fine committing even more monopolist behavior in the very related and overlapping market of B"
This makes claim makes pretty little sense to me. AI search and Google web search (ads) are already stepping on each other. I see no reason that Google wouldn't be worried about antitrust on AI search if they're worried about antitrust action in general- which they clearly are.
