What configuration is indicated by a generator with a neutral wire?

Having a neutral wire means the generator is wired in a wye (star) configuration. In a wye setup, the ends of the three phase windings join at a common point—the neutral. That neutral can be grounded and provides a return path for current, allowing line-to-neutral voltages in addition to the line-to-line voltages. In a delta configuration, the windings form a closed triangle and there isn’t a separate neutral conductor, so you don’t see a neutral wire. An isolated setup has no solid path to ground or a neutral reference, and Open Delta is still a delta arrangement with a missing leg, not associated with a neutral conductor.
