Looking to use Table 310.15(B)(16) for MI cable ampacity, but it only lists MI cable in the 90 degree column. Does this mean there is no 75 degree ampacity rating for MI cable? In order to use the 90 degree column then all lugs need to be 90 degree…. And anything else or just lugs?

You use the 90° column value for adjustment and correction.
You use the 75° column value* to establish the minimum size conductor to correlate with 110.14(C) terminal temperature limitations.
Circuit ampacity will be the smaller of the two.
*This assumes terminal temperature limit is in fact 75°C
