Healthy or not, Itachi still can't spam his MS powers like that, and he would be dumb to do so. He used Tsukuyome on Kakashi because he saw him as a threat. Given that Kakashi managed to surprise him later proves that Itachi was right to do so. It also proved an excellent deterrent so they could easily escape.

Unless Evil Itachi was hellbent on becoming blind within a few months like Sasuke, he would still be very conservative with his MS powers.
