I second all that Dan said.

it's very often fungal infections, which are VERY common in tomatoes.

==>> ive grown Ts for 50 years.. and have NEVER seen this.. i wonder how common this issue really is ... maybe its a CA or TX thing....

it looks like herbicide or spray damage to me..

where is OP.. big city name.. and how about some pertinent info beyond a curled leaf... some info to help us.. help you ..

It's a matter of luck. Or bad luck. Just about every state extension service has a page on tomato fungal infections.

Look around. Here's one for MI - https://www.canr.msu.edu/resources/michigan_fresh_tomato_diseases_in_the_home_garden

So it's NOT safe to eat these tomatoes, even if they could fully grow, correct? Assuming the fungal element is not directly grown into the tomatoes, the nutritients might be compromized due to fungal destruction and alter the chemical compounds of the fruits? ???

Agree with Ken. Other than herbidice damage, curly top virus is the only thing I know of that would cause this severe twisting and curling. There are many fungal issues tomatoes can get but in my experience they don't cause the damage seen in the photo.

Herbicide damage can result from you or your neighbor spraying weeds in their lawn, along a fence, on patio cracks. It can come from using contaminated hay or straw as a mulch. It can come from amending your soil with animal manure or compost made with manure. The plant may grow out of it, or may not.

If it is curly top virus, which is spread bg leafhoppers, the only thing you can do is pull up the plant and trash it. Viruses are not curable.

Whether fungal or virus, the tomatoes are safe to eat. I have no idea about whether nutrients might be compromised, but you personally aren't going to get a fungal infection or virus from them and they should taste pretty much the same. I would hope you're not relying on nutrients from tomatoes in any case. I suspect herbicide is NOT the issue, if you have other things in the vicinity that are unaffected. Look around. Of course, while herbicide can come either from a neighbors spray drift, it can also come from contaminated compost (e.g. pyralids). Have you amended these tomatoes with purchased compost recently? True that while wilting and dying leaves is a common symptom of fungal infections, curling leaves is a bit different, and can certainly point to a virus. Broad mites are another possibility. They inject toxins into the leaves that make them curl. Unfortunately, these mites are almost microscopic, so they'd be hard to identify. Look VERY closely at the leaves, maybe with a magnifying glass. In principle, insecticides could help with both virus carrying insects and broad mites, but you'd need to get one specifically labelled for them.

I'm guessing a virus too.

How many plants are affected? What variety is it?

IMPE with tomatoes and viruses, they don't produce fruit once infected, and some varieties can be very susceptible.

all Roma tomato plants are affected. It's hard to identify really what happened, for only are the tomatoe plants planted in a sginle bed far away from other vegetables and plants. Other vegatable are fine.
