たり sentence without the final たり
I have no idea what you're implying the matrix has to do with anything. Seriously though, I'm not a linguist, but if you had read the question properly you would understand my answer. In the last sentence, the questioner asked if it also would "have been ok to finish off with just 食べます", in essence just removing つもり and conjugating the verb because the sentence is written in ですます調. The past conditional 〜たら can mean both if and when. In the sentence, it's pretty clear that they're talking about if it rains, because つもり followed by a nonpast conjugated copula implies future action.
