I think because of how few products Google has that actually make money this would actually be quite difficult in that it would be surprisingly hard to divide up Google into multiple companies that still have sources of revenue, much less were still profitable.
Even if rather than actually "breaking up" Google, you simply tried to force some type of debundling like with Microsoft, this would still be difficult. Take the case of Android being bundled with Google services for example. Android itself isn't what makes Google money, so preventing them from integrating it with sources of revenue would probably just kill Android.
