I just learned about left-handed drill bits that can be used to removed screws with stripped heads. However, without those lefthanded drill bits available, can I use the normal (right-handed) drill bits, and the Reverse function of the power drill to undo a screw with stripped head?
My DeWalt power drill/hammer/driver has the Hammer function, so combining with the Reverse function, it would additionally help?

NO it will not grab onto the head.
The reason the reverse bit may work is because the cutting part of the bit is designed to cut into the surface, when it starts to cut or grab it then turns the screw counter clockwise.
A normal bit will just spin and not "grab".
No the hammer function will not help.
A screw extractor set is far better then a reverse drill bit.
