If I were the EU, I would perhaps consider slapping restrictions on Google's Chat AI (say, Bard) as being a separate field (AI-Assisted Search) being propped up by a monopoly in Standard Search. That would hurt Google's dominance quicker than any other action. Same for the DOJ.
Remember how much trouble Microsoft got into for having a basic monopoly on desktops with Windows, and trying to bundle Internet Explorer? Replace Windows with Standard Google, and Internet Explorer with AI-based Google Search. You'll cut Google off at the knees with that move. And even if they survive the ~4-5 years litigation, they'll be severely hampered, kind of like how Microsoft was with the mobile phone market.
