Considering that Ainz has gained the majority of his spells through [Dark Wisdom], which appears to involve defeating/killing a spellcaster who is using the spell, probably a lot of the spells he knows are 'loser' spells.

Or at least not "win" spells.

Rubedo probably has insane spell resistance and the ability to get in a spell-caster's face and shut him down in short order. So there are probably only a select few spells which would even be useful against her, and not long to cast those spells before she wiped the floor with the caster.
