We saw Deanna speaking with her father in an illusion in her mother's mind (damn telepaths!) and he has no accent either.
Maybe the reason that Deanna has an accent and Lwaxana does not is that Deanna is actually speaking English, and Lwaxana is speaking Betazoid, and we hear her through the universal translator.
That's a good thought, but you'd think being a telepath she'd be able to learn a language pretty quickly though. At least that's how I see it.
