You've narrowed the Google example down to them having a link in their index as a search result. People can already sue for keeping links to certain sites/data (pirate sites, personal data etc.) Somewhat closer for comparison, you could already sue Google if they misrepresented the links or content provided by the search, if it differed significantly from the site.
You could already sue the browser for misrepresenting/modifying the info of a given web page, and/or injecting malware. They didn't create the website or content, we all know that.
You can sue any company who is the creator/owner of information. Chatbots are technically creating new information, so whilst a grey area from purposeful human misinformation, the companies are far closer to owner/proprietor of information than the other examples.
