A plane-of-existence is different from an alternate dimension. In esoteric cosmology, a plane other than the physical plane is conceived as a subtle state of consciousness that transcends the known physical universe. An alternate dimension literally is just another term for parallel universe. Madara's Limbo: Border Jail projects his shadows into a parallel dimension world known as Limbo, that can still somehow affect Naruto's.

So no, it doesn't necessarily need to give off chakra just because everything in Naruto does. It could also possess the ability to conceal it's chakra. Also, as I mentioned, it could exist in a different plane, so detecting it would be virtually impossible for regular sensor types, hence only Boruto's unique dojutsu can only see the entity, but not sense it. So in this case, it doesn't even matter if it gives off a chakra signature - Naruto and Sasuke may not be able to detect it. Of course, there is a possibility they are already aware of some sort of malicious presence after Boruto: Naruto the Movie, as I would assume only SPSM can detect a trace of it. Sasuke would probably need to directly see it to be aware of it. Then, even if they can see/sense it's presence, they cannot truly defeat it.

Boruto's ability is not overpowered, because it only allows him the ability to completely destroy foes like the entity, which exist in non-corporeal form. It also allows him to see through dimensions and planes, kind of like Sasuke's Rinnegan, though it doesn't give him any overpowered techniques. In other words, it doesn't grant him divine powers that one-shot foes.

It would be dumber if Boruto's abilities were just copy/pasted from the nearest Naruto/Sasuke near you lmao, turning the combat in the Boruto manga (when in relation to the new generation) once again into a clone of a DBZ clone.
