Yeah, no problem.
The stuff about てみろ being a conditional it got right. It’s used for something bringing about a certain hypothetical result, typically. For example, I used it for if it rains, then it will hypothetically bring the result of a game getting canceled iirc.
In the thing @WeebPotato linked, they use it like
彼に見つかってみろ。大変な目に会う
Which is saying that if you are found by him, it will bring the result of 大変な目に会う
And 彼と飲んでみろ。朝まで帰れない
Which is saying that if you drink with him, it will bring the result of 朝まで帰れない.
I think GPT did a poor job of choosing an example sentence for it, though. It could be used as a conditional with 食べる but you really need to make it a full sentence to showcase that. The whole point is that there is some hypothetical outcome, so if there isn’t one written it’s kinda wrong to say it can be interpreted that way since in that case you would interpret it as an order instead.
EDIT: Since this is something that looks like is harder to find online and I just realized the grammar blog I linked in my test is no longer up, I’ll show a few more sentences from my books. I just searched for 言ってみろ
context: MC got a step sister and was expecting her to be elementary, but she was actually a highschooler who happens to be at his same school in the same grade…and beautiful of course. MC is thinking to himself that if he let people know of that situation, it would lead to the latter sentence.
