Who trains and programs the AI?

You?

No, you don't. Additionally, you seem unaware that AI has just made stuff up, like that a reporter had died, even faking links to news articles. Who programmed that in? Because, LLM's can't create fake links. All they are able to do is weight text samples they've been trained on, and fake URLs aren't amongst those samples, so that ability to maliciously harm people and fake URLs has been programmed in.

Don't forget AI is a weapon pointed at you, that you can only grab by the pointy end.
