No, let me rephrase: often, problems can be solved with words. In those cases, the conversational agent wouldn't link to anything. It would just solve your problem.
But if a problem being solved necessitates linking to something, then what kind of problem is that likely to be? Usually one where you need to stare at something, mull over a bunch of details, and make a decision. What kinds of webpages are those? Usually — for public clients — those are product pages.
(Another potential use-case is that a conversational agent could help people configure to software/services by deep-linking to configuration screens — but that's not really a thing Google Search could integrate with.)
