G force is also a function of how hard you pull on the elevator. If I want to fly straight and level I will have to adjust the elevator to achieve exactly 1 G. If I roll to 60 degrees bank and I want to stay level then I will have to pull on the elevator until I have exactly 2 G. If I pulled to 9 G I would definitely wouldn't stay level.

So for level flight G force is a function of bank angle.

Now to achieve a specific turn radius does imply a given G dependant on speed. I can't just pull that G though, I need to bank, otherwise I'll just pitch up. If I match my bank angle to the required G then I can stay level ( if I'm not level the radius will be wrong anyway).

It's normal in flying to do it the other way round though, choose a bank angle and apply G to maintain level, climb, or descend as required. If a smaller radius is required then increase bank and adjust G to match.
