So the app developer has to be able to demonstrate they followed some form of best practice with regard to user data.
I’m having trouble thinking of any other type of work that manages to escape all liability.

I think you're downplaying the requirements of this law. You should read it, it's pretty onerous and carries decades in prison with it - even GDPR didn't go that far.
One interesting caveat, however, is that at least as written, I can't find anything imposing penalties for simply not filing the reports this law claims to require after all of the expensive audits etc it wants. It only imposes penalties for lying on the reports. I'm not sure if that was an oversight on the author's part or if that's intentional though. Any final version would likely "fix" that issue.
