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.
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.
What's the non-coincidence?
