Kaguya was attempting to protect the world from her Clan. she consumed the fruit of the shinju and got god like powers but her clan are Thief's and constantly power up. so she created the zetsu as an army of individuals that can do the same. the zetsu's parasitic abilities allow them to turn into anyone they touch and gain access to chakra nature and kekkei genkai. so essentially that means an army of weaker Kaguya's

in my opinion if Sasuke summoned her and explained that Isshiki took Naruto. she most likely would help them fight. she kind of lost her mind when her sons turned on her but she also kind of viewed naruto and sasuke as her sons. so she might get mad that Isshiki took Naruto and as such might agree to go with sasuke. if kaguya went with sasuke than Isshiki would have no hope of winning
