I’m using a Nikon D750 and want to know whether Bulb mode has a built-in maximum exposure time, or if the shutter can stay open indefinitely.

You can use the time exposure mode as long as you want - at least, until your power source is exhausted. You'll gradually get more noise as the shutter is open longer, from the sensor heating up, so it's seldom done to such extremes. (In the film camera days, very very long exposures, while uncommon, were done much more often than they are done today, e.g. for star trails.)

On the Nikon D750, Bulb exposures are not limited by a fixed built-in time. In practice, the shutter can remain open as long as you keep it activated, until the camera’s power source is exhausted or you stop the exposure.
For very long exposures, image noise usually increases as the sensor heats up, so extremely long Bulb shots are possible but often not ideal for image quality.
