Q.Worm or larvae killing tomatoes
The leaves on my tomato plants started curling and turning yellow. On closer inspection, I found small black/grey worms or larvae cocooned in the curls. As they eat the leaves, they turn yellow, then die. I wasn’t sure if this is a combination of the worms and a blight (it looks like blight), or if it is just the worms. They also make tiny pinholes in my tomatoes and kill them.

It sounds like you have tomato pinworm. This article will have more information about them: https://www.gardeningknowhow.com/edible/vegetables/tomato/tomato-pinworm-control.htm
