The way I see it (guessing, not knowing anything specific), the better commercial VPN services -- at least in or ensared into U.S. law -- may not keep logs, in general. But when a three letter agency with relevant authority (being more generous WRT some VPN services, maybe only unavoidable authority), asks for logging for specific users or perhaps some other narrow logging profile, then such logging starts and is made available.
