jigen may not have had the eye but isshiki who was inside of his body did and that likely meant he could use atleast some of the eyes abilities that dont need direct line of sight. similar to how almighty push,mind reading,chakra absorbtion and many other rinnegan abilities dont need you to use the jutsu directly with your eyes and its essentially a jutsu that requires you to have the eye to utilize.
