The paralysis applied by the lich's touch attack is likely referring to the lich's built-in negative energy touch attack, which it is allowed to deliver via natural weapons.
A monk's unarmed strikes are considered natural weapons. Therefore, the monk-lich can add the negative energy damage and, by extension, the paralyzing touch to his unarmed strikes.
