Alisaie's sword looked to be a similar model to the Dark Knight's Balmung, which is ironically the same model used for the Padjali DRK sword.... So I don't know. It may be unique to her like Y'shtola's staff.

Her animations were the generic GLD sword swings used for weapons that don't have their own special animation and stances, like crafting and gathering main hand gear.

But her comment about studying multible schools of magic pretty much cements that she's some sort of proto-Red Mage.

It makes me wonder if Red Mages use swords of aetheric energy as their main hand, or if that's just Alisaie showing off.
