Elsweyr is part of the Dominion but you dont see Kahjiit as Thalmor because the Thalmor are the ruling party of the Dominion and they are strictly Altmer. The Altmer overlords basically dominate the Bosmer and Khajiit. So technically, Khajiit aren't "part" of the thalmor, they're controlled by the Thalmor by being part of the Aldmeri Dominion (Which the Thalmor are the ruling party of)
