But a tomato isn't even an actual fruit...

"Actual" refers to the ordinary "plain English" meaning. Under the "plain English" definition, i.e. non-technical, non-domain-specific, a tomato is a vegetable.

It's a botanical fruit, but an actual vegetable.

That feels like a rather tactless choice of phrasing in the headline, given that there are people literally under fire by Israel right now.
