This is actually the only possible answer IMHO. Humans are Turing-complete, which means the best we can do is give them training and guidelines and trust them.

This is actually the only possible answer IMHO. Humans are Turing-complete, which means the best we can do is give them training and guidelines and trust them. Even so their training can be subverted through social engineering. What we're talking about here is social engineering of LLMs. That's currently pretty easy. It will get harder but it cannot be made impossible.
