I'm an attorney who seldom sees LLC's or corporations formed by lawyers.  Mostly the paperwork is prepared by CPA's or people who call themselves "paralegals," if not by DIYers with an Internet connection and printer.  I have filed a few in the last 40 years, but I don't consider myself as having an ongoing client relationship if that was the last work I did for someone.  So that's my take on your guess about likelihood.
