A clan created whit the name of the bigger bad of entire manga, makes sense, more or less, but Kimimaro haves a blood relation ship whit her, not probable. In the best of options, the most plausible situation is some one, near of Kaguya, like a vassal or similar haves a lot of worship to her, then this guy creates a clan under the name of Kaguya in homage to her goddess.
