If you sell food, in a food stall, labeled as food and you add a disclaimer that it is toxic and will make you sick. You are still selling toxic food and you are liable for it.
Google is pretending to give answers to your questions. They offer you a service about answering questions. And then they add a disclaimer "we do not answer questions just write bullshit". That is still fraud and Google should be liable for it.

Tetris is non-deterministic and it is not banned like millions of other programs. I do not follow you.
To add to this, a Google search now is answering your question in an incorrect way rather than merely bringing you to a site with incorrect information on it.
They are also no longer covered by safe harbour provisions because it is them answering it, not some content they refer you to.
