Once the Taijutsu master of the duo is dead, she has much better odds against Momoshiki. Also, thousands of Zetsu can still physically overwhelm Momoshiki, using their spore power to continously drain his chakra and reproduce. And since they don't have chakra or powers of their own, turning them to edibles at worst makes him break even with chakra use. Which means Zetsu are excellent at keeping him busy.

As to Kaguya's immortality, it doesn't really matter does it? Momoshiki has Chakra Edible creation, he can absorb and consume her chakra until she reverts to Gedo and then turn the Gedo into an edible. Surely he first needs to defeat her to be able to do this, but with Kinshiki being a taijutsu expert (Considering the whole Weapon Creation thing he has to be) and her being a primary Ninjutsu user (and Momoshiki absorbing and returning that), Momoshiki and Kinshiki have the better cards.

As to All Killing Ash Bones and her hair, one can argue that since they're physically part of her and since she has chakra, these objects have chakra, can be considered Ninjutsu and absorbed. Whether this is true is debatable, but clearly Kaguya wasn't taking the risk.
