Section 230 has been subject to numerous reforms and proposals in recent years, so yes it's a very real legal issue that platforms are keeping an eye on. FOSTA is an example, in which platforms all had to make changes and now constantly take down posts related to those acts. Another proposal to amend 230 ("Ending Support for Internet Censorship Act") is that platforms are stripped of their legal liability protections for what is posted if they cannot prove they are "politically neutral".
Section 230 only immunizes service providers for the contents of users' posts, not its own content. It can't immunize Google from being responsible for Gemini's output.
