I’m not sure this is a huge deal. The main reason you’d use an LLC is to hide your information from public records, not the government. That use-case doesn’t seem to be impacted.
Of course a data breach would be unfortunate, but the same could be said about the IRS or any other government agency you regularly interact with. Generally speaking, various US agencies already have a lot of information about US citizens collectively, and I don’t think anyone was promoting LLCs as a way around that? Maybe I’m wrong.
As a one-person entity, it’s still very annoying though.
