They have lawyers, but everyone has lawyers over a certain size and the NHS is huge.
As for billing, who would they bill - I've never had a bill from the NHS or even heard of someone getting a bill from the NHS? In some parts of the UK you have to pay a small amount for prescription medicines but that doesn't go to the NHS etc.

It literally is "free at the point of delivery".
Edit: The NHS directly employs about 1.4 million people https://fullfact.org/health/how-many-nhs-employees-are-there... - and that's not including people who work in GP practices or dentists or opticians who do NHS work but aren't employed by the NHS.
