The tariffs might be a bad idea, but this accusation is ridiculous. For a simple methodology like this, it's trivial to prompt engineer a LLM to produce the same response. It doesn't mean that that's how the administration came up with the policy, any more than a LLM getting the same (correct) solution as a student on an assignment means the student used a LLM on that assignment.

The takeaway from the X-poster being "it's good that they're using LLMs" is hilarious. Why praise the method if the end result is so bad?
