If you do something, it's ultimately you who has to make sure that it is not against the law. "I didn't know" is never a good defense. If you pay with counterfeit cash, it is you who will be arrested, even if you didn't know it was counterfeit. If you use code from somewhere else (no matter if it's by copy/pasting or by using Copilot), it is you who has to make certain that it doesn't infringe on any copyright.
Just because a tool can (accidentally) make you break the law, doesn't mean the tool is to blame (cf. BitTorrent, Tor, KaliLinux, ...)
