A person is also not like a hammer. Both persons and AIs have been known to mis-interpret instructions, the normal way to deal with that is either to terminate your relationship with the people (or to terminate the AIs and train up better ones). Hammers don't mis-interpret their instructions, they are wielded by a person who is in control.
You can keep 'trying to explain' but then you should use words according to their commonly held definitions otherwise it becomes really hard to have a conversation.
Imagine the human equivalent: I hire John. John is a capable, and competent guy. He's also got awesome computer skills. I tell John to 'go out and find me some good information on my competitors'. As a result John hacks their servers and comes back with all kinds of goodies. Six weeks later I notice what John did. I don't fire him, nor do I take any responsibility myself. But I do make press releases about what John did, in which I'm careful to craft the image that John has these capabilities and that we as a company are for hire.
This was an advertisement, not a confession of a crime.
I would also not call an animal or an alien a tool. But an "AI agent" is a fancy term for a particular kind of very powerful computer program, it is not a being.
