The point is that laws are useless without enforcement. There's a wide body of civil law that depends upon the plaintiff to assert their rights. The government isn't going to go monitoring every private transaction to ensure it conforms to every applicable law. We don't want them to do that - in general the government should stay out of private transactions, that's what makes them private. And the law usually requires multiple attempts and back-and-forths to ensure that everyone has had a chance to rectify the situation before it goes to the court system. Again, this is a good thing.
But one side of the transaction is much more able to put up with convoluted processes and paper trails than the other. A corporation can amortize the cost of the paper trail across many customer interactions and build systems to handle it automatically. It can hire employees to do nothing but sit on the phone, and build delays into business processes that will make most customers give up.
These sort of LLM startups just give the same economies of scale to customers seeking redress. Yes, it'd be easier if the whole process didn't exist - there's an old joke about LLMs generating e-mails to sound longer and more impressive than they need to be, and then another LLM summarizing the e-mail back into one sentence that isn't really what the original person meant. But the problem is that each incentive along the way makes the company better off if they get the customer to go away, while each incentive for the customer makes them better off if they don't go away, and so you get an arms race between them.
