I'm not expert in mold but ventilation should help. If mold fell in your sump it would probably be killed instantly, I can't see it causing a problem that way. Applying a layer of silicone to seal it off might work or you just might wind up with mold growing under and at the edges of the silicone. Still that would be less problematic than trying to apply paint there, especially water-resistant paints which typically have a lot of potentially toxic volatile hydrocarbons. If the problem turns out to be hard to solve you might start a new thread to ask about it.
