Yes, but an employee can still file a wrongful termination lawsuit if they believe that the "no reason" termination was bullshit and that they were actually fired for an illegal reason.
Like, if someone decides to come out of the closet on social media and their co-workers find out and their boss hears about it and fires themthe next day but claims that it's a "no reason" termination, it would certainly raise suspicion that they were actually being fired for being gay and they might win a wrongful termination lawsuit, even in an at-will employment state.
