My question involves business law in the state of: Georgia

As an independent consultant (IC) using 'X' LLC had signed a NDA with 'Z' LLC. Z LLC didn't want to work with me. However, was providing my service to 'B' LLC. Again, representing for 'Z'. So, I'd informed 'B' of this sudden change in contract and they agreed to work with me directly. However, I signed a contract with 'B' using a new LLC - 'N'.

'Z' is filing lawsuit stating that X has breached the contract. Any validity to this ?
