2013 Prius Hesitation Help ?

Reduce your exhilaration while driving. Some might call that distracted driving!

Seriously hesitation from a stop on a gen3 can be a severely worn hv battery or a bad head gasket misfiring on the transition from engine stop to running.

Watch the startups from a traffic light when the hv battery level is really low and compare to stops when the battery has a better charge. Often a really bad hv battery will discharge fast at a light.

If it is a head gasket and hesitation is often happening at lights, the coolant level is probably going down.

Other misfires and sensor problems like a bad maf would create codes.
