Current go first thrawn "AI" move
I searched and looks like it's been changed since launch. On offense using auto, he always gives TM to a random toon first round then fractures the second, again random.

At the start of the battle, if no ally has a debuff, he will use fracture, no matter if the enemy is buffed or not.
If by the time he takes a turn any of your toons is debuffed, he will cleanse first
