If the tomato vine was damaged enough to kill it, then no, the tomato will not ripen. If the vine survived the frost and the temperatures have gone back up to optimal ranges then the fruit may yet survive. You can cover the plant at this point to protect it and speed up ripening. Is It Okay To Pick Green Unripe Tomatoes? Yes.
Beside this,How big are black spots on the underside of leaves?
Tiny black spots on the underside of leaves appear. They are small in diameter. To be more specific, these are around 1/16 to 1/8 inches (1.6 to 3.2 millimeters), with a dark brown margin and lighter gray or tan centers. The spots may grow larger as the disease progresses. You might even see the spots merging together.

Tomato plants can tolerate high levels of leaf loss from leaf spot diseases without affecting the number of tomatoes produced by the plant. Use cultural control practices like staking and mulching plants, and pinching off infected leaves to keep leaf spot diseases in check.
Also question is,What happens to tomato plants in the winter?
Tomatoes are referred to as tender perennials, as they will generally succumb once temperatures drop, especially once frost hits. Other tender perennials include bell peppers and sweet potatoes, which will also die back once frost is in the forecast.
Why are my green tomatoes not ripening on the vine?
What you may not know, though, is that low temperatures can harm mature green tomatoes (the full-sized ones that just haven’t turned red yet) to the point that they won’t ripen, even if the plant is covered.
