"OH"OH is not a polyatomic ion because it is not an ion.

Explanation:

However, bb("OH"^"-")OH- (note the negative charge) is a polyatomic ion.

A polyatomic ion is an ion composed of two or more covalently bonded atoms.

The prefix poly- means "many" in Greek, but even ions of two atoms are commonly called polyatomic ions.

In your equation, "KOH"KOH is an ionic compound consisting of "K"^+K+ ions and "OH"^"-"OH- ions, and the "OH"^"-"OH- ions are polyatomic.
