That does not look like verticillium to me. Branches just
wilt, and once they do, they do not come back.

The plant is a little twisted up, but the leaves look quite
healthy. So far, it does not look like CMV or similar virii,
either. With those, the leaves themselves twist up and roll
a lot more than that, and new leaves are usually quite small.

I have seen plants that look like that, but I do not know the
cause. I would leave it alone for a couple of more days, maybe
a week, and see what happens. Maybe it starts growing
vertically again.

(It just looks like it is growing unevenly, with some parts
growing faster than other parts. I have had plants where
the top of the main stem looked like a clenched fist.
I thought, "Oh no, 'rosette condition'," which is a symptom
of particular diseases and nutrient imbalances, etc, but
the thing eventually grew out of it, and the plant ended
up looking like a normal tomato plant.)
