The solution is simple → don't use automatic code suggestions/PRs. There must be a human involved that suggest a piece of code - and he/she should be fully responsible for it (if there is an error/bug in the code - he/she's at fault). That should be the way, at least, until AI is proven to better at writing code than humans.
