Light does have a parallel to reverb - reflection.

I don’t think that light eperiences comb filtering. Is there a case where we perceive two sources of light to cancel each other?

polarized light can have interference/comb filtering with other polarized light.

Going on the polarization tangent, reflection polarizes too, so hypothetically you could cancel light reflected off the stage using polarized sunglasses.  That however wouldn’t equal our issue of unintended cancelation, due to energy vs air pressure.

Light can have comb filtering if it’s coherent.  Lasers produce coherent light, of course, which is why they’re used in holography.  Both holograms and the images they produce are interference / comb filtering patterns.

About reflection, I would tend to say that it’s more like an echo than reverb.  Of course, you could say that reverb is nothing more than a whole lot of superimposed multi-bounce echoing. So I guess that in a room full of mirrors, you could have actual optical reverb.  Because of the speed of light, the decay time would probably be in the microsecond range.
