No need to maintain a force field or anything like that. If you have enough gravity, you'll hold an atmosphere.
Now, if you are *not spinning*, you have a different problem.
Earth is spinning, and rather fast; a spinning liquid iron core will generate a magnetosphere to keep the solar wind out, and the air in.
If you don't spin, you lose your air to the wind.
If you do spin and don't have a large moon to act as a stabilizer, your axial tilt goes crazy (this is something I read long ago, as a potential term for the drake equation to explain the lack of other beings -- long ago before we really understood the size of the problem -- saying that if you needed to be hit by a large planet to spin and be lucky enough to not be destroyed, and get a giant moon in the process, that was going to be really rare, which might explain why no one is around to be seen yet.)
For this to be a weapon, the spin needs to be controllable. It has to be aimed. So it needs enough spin to be able to turn, enough axial *instability* for the angle of turn to change, and enough control over that to aim precisely where they want to.
... So, they have some Force user / Equus Cutis Alicornus or something to control the tilt and rotation of the planet?
