I don't think lich would be the best way to describe him. Lichdom comes from necromancy and the evidence supports him being a master of restoration.

Cures an incurable disease. Check.

Creates life. Check.

Restores his own cells to live forever. Check.

That last one is what I see. He displays extremely powerful restoration magic so I personally don't see it as that much of a stretch that his longevity is from restoration, not necromancy.
