What specifically is the proposed mechanism by which these tomatoes would be harmful to health long-term?

Nothing ever happens in isolation. Thinking that the only change is more vit D is reductionst. There could be billions of other interactions changed across the plant due to a "simple gene change for vit D".

I remember one mice or rat study which shown that feeding GMO grains to mice cause liver or kidney issues, while non-GMO did not.

What about the GMO grains caused them to be harmful?

these are knockout mutants, that means genetic function is reduced.
