Not limited to physical products. It's common sense to have a lawer if you do business. There is all kind of nasty stuff that will harm you; and you yourself might be even the first one on that list. A laywer should also be around check how you not break any law yourself.

You might unwillingly break someones IP yourself, or go against some easy to find trademark or patent. Or your businees might be based on some idea which is actually illegal in some aspect.

And if your business is running, you need someone to take care of customer-complains, copycats, piracy, problems with employees and partnered companies... There is so much that can go wrong, so many toxic people who wanna milk you for a cheap dollar. It's like the real world-version of anti-malware-software. If you don';t know exactly what you are doing, it might be healthier to have some good protection.
