Is it necessary to equip the empoisoners with either skull talismans (for item-spellcasting) or skull staffs to prevent fatigue?

No. In magic dominion at least they can easily cast enough to beat almost any indy. (Notable exception being knight commanders; even against bodyguarded priests they usually seem to win.)

Skull staffs, on the other hand, allow you to cast raise skeletons which makes them very dangerous even against human controlled opponents.
