Non-lawyers aren't banned from giving legal advice because lawyers are trying to protect their jobs, they're banned from giving legal advice because they're likely to be bad at it, and the people who take their advice are likely to be hurt.
Yes, in this case, it would just be a parking ticket, but the legal system runs on precedent and it's safer to hold a strict line than to create a fuzzy "well, it depends on how much is at stake" line. If we know that ChatGPT is not equipped to give legal advice in the general case, there's no reason to allow a company to sell it as a stand-in for a lawyer.
(I would feel differently about a defendant deciding to use the free ChatGPT in this way, because they would be deliberately ignoring the warnings ChatGPT gives. It's the fact that someone decided to make selling AI legal advice into a business model that makes it troubling.)
