I think what we are seeing here is this: there is no such thing as the Los Angeles Sheriff. So there is probably no legal issue with using that name.
On the other hand, there is a Los Angeles County Sheriff -- so that's probably where the issue is. A real entity might have an issue with 10-8 using their name in a television show.
Just a guess. But it seems logical.
