I don't, as it happens, but clearly you do so I was attempting to address how I would rule if I did consider 7♥ an LA.

This makes no sense to me. People do not tend to make grand-tries "immediately". I could believe a slow 5♥ might have been intended as a grand-try (though even that is a stretch), but not a fast 5♥. It is only the UI that makes a grand-try even remotely plausible, so I'm certainly not allowed to act as though that's what partner intended.
