Is it accurate that general relativity may predict nonlinear but not chaotic spacetime?
I don't know what a nonlinear spacetime is. The Einstein field equation is nonlinear in the sense that two different spacetimes, although each a solution of the equation, their sum would not be a solution.
There is a spacetime which is solution of the Einstein field equation which is believed to be chaotic:
