Yes, you're missing quite a lot. There are many ways to gain turn/rebuke abilities. For instance: Paladin (including Paladin of Slaughter and Paladin of Tyranny), Dread Necromancer, Ur-Priest, Blackguard, Knight of the Raven, Apostle of Peace, and Death Delver classes all gain turn or rebuke as class features.

The restriction that you cannot be (true) Neutral without worshiping a (true) Neutral deity is particular only to Clerics, and does not generally apply to all those classes I listed which gain turn or rebuke ability.
