I have some experience in this area. In 2017 Delaware amended their General Corporations Act & Limited Liability Act expressly authorizing corporations & LLCs to maintain their books and records on blockchain - shortly their after I became the 1st attorney to memorialize smart contract addresses in documentation filed with the State.
More recently I obtained a provisional patent for a system and method for managing books and records (e.g. legal documentation) using blockchains for real-time legal compliance, and though this could have been independently developed I elected to integrated it into the ENS protocol by leveraging subdomains and records. See: TOKENIZATION LLC - Mint/Own/Manage a Delaware LLC on ENS
Other lawyers in the space have done similar things to scale legal protections (mint a LLC protected series/tokenized ownership) but never touched onchain legal compliance much less integrated into ENS protocol.
For illustrative purposes, ENS DAO uses subdomains effectively for the organization but both subdomains and organizational resources could be mapped to the parent ens.eth, or a preferred name, effectively using records. In my linked post you’ll find the below image - something of a legal oracle of legal entities (organizations) which map books and records (organizational legal data) to ENS.
