My understanding is that LPL is not still practicing (he says he's retired, to focus on security work), but I'd guess he knows someone, if McNally didn't already have his own lawyer.

Even if he was practicing, if he were to take this case it would pretty obviously expose who he was.

So no matter what I would expect LPL would get someone he knew/equivalent to take the case.

I mean, it's not exactly a secret. If you really want to know you can look it up online. He even has a whole talk he gives about why he generally doesn't reveal his identity. People send him packages with trackers hidden in them, hire private investigators to follow him with bogus stories, etc.
