I think your tulpa is playing tricks on you. A shell around the Earth will have no effect on the interactions of bodies within it, or their interactions with everything outside the shell.
You’re correct. There’s other ways to guard against collapse of an empty shell, it’s a similar scenario to guarding against collapse of a Dyson sphere.

It could counteract the gravitational pull which would cause the surface of a hollow Earth to collapse otherwise. Edit: It would not :-(
A spherically symmetric shell has no effect on the gravitational field inside. It will not pull the surface of a hollow Earth outwards.
