On the current version of the mod, it seems that everything in dark rooms, including tolls and interactable bosses, are doable without having the lantern. I've only tested with the broken lantern option, but I assume this must also be happening if dark rooms are randomized. Interactability does not seem affected by how many (if any) lantern fragments the player has.
