Would the same hold for other forms of communication and information retrieval, or should only LLMs be perfect in that regard? If someone is persuaded to commit suicide by the information found trough normal internet search, should Google/Bing/DDG be liable?

Do you believe a book should be suppressed and the author made liable, if a few of its readers commit suicide because of what they've read? (And, before you ask, that's not a theoretical question. Books are well known to cause suicides, the first documented case being a 1774 novel by Goethe.)
