Here's my advice. Care for them as normal, because they are acting normally to unfavorable conditions.

It's too hot for the plants, and they don't like it, and they are dropping flowers because they can't pollinate reliably above 95 degrees. The dry curly leaves are most likely also due to the extreme heat. The leaf curl is most likely what they call tomato "physiological leaf roll" and is a response to some sort of stress - like you would see from high temps, amongst other things.

When the temps drop back into the 70s-80s, they will go back to their normal productive selves and begin setting fruit and ripening fruit as usual.

Thanks!!!! I knew the heat was an issue. You are right.

Thank you so much, person who asked and person who answered this! My tomato plants are doing the exact same thing: curly leaves, blackened flowers and a few green tomatoes. But it's also hot as balls here so now it all makes sense!
