The Khajiit don't worship the Thalmor. They're greatful thry brought the moons back, but they don't think of them as gods amoung men (or Felines in their case). So it's very unlikely they fight for them.

The Nords have most of the same values as the Empire (or atleast they used to) so they fought with them. While the Khajiit don't care for the Dominion's Elven supremacy ideals, so they probably don't fight for them.
