Your posting makes no sense. Hereīs how itīd logically go:

Fight starts.
Hit stops time.
Within the 0.5 seconds, he approaches Goku and decapitates him.
Time flows again.
Blood everywhere.
The end.

Thatīs how overpowered Hitīs ability is when you apply logic to it. There is no way to conter it. Again, we have the perfect example with Jojo, where Jotaru was only able to defend himself because he learned to stop time, too. Goku has no control over time whatsoever, so heīs helpless. Itīd be different if Hitīs power was to slow down time. In that case, Goku could actually increase his own speed to the point whe heīs stil too fast when slowed down by Hit. But thatīs not what weīre dealing with here. Time is stopped, fullstop.
