Which spells the AI will never cast?

This, of course, depends on the battle. Skeleton spam is quite capable of winning battles and when you're aiming for that you're glad they do it so reliably.

One or two death mages sitting way in the back summoning skeletons when they could be doing something useful is annoying though.

I have noticed that even a couple of undead can make AI priests/mages ignore anything else. One D1 mage spamming Animate can keep priest-mages spamming banishment instead of slaughtering your real troops.
