Non-rotational and rotational metric tensors

General Relativity...

Non-rotational spherically symmetric body of isotropic perfect fluid Einstein tensor metric element functions:
$$g_{\mu \nu} = \left( \begin{array}{ccccc} \; & dt & dr & d \theta & d\phi \\ dt & g_{tt} & 0 & 0 & 0 \\ dr & 0 & g_{rr} & 0 & 0 \\ d\theta & 0 & 0 & g_{\theta \theta} & 0 \\ d\phi & 0 & 0 & 0 & g_{\phi \phi} \end{array} \right) \; \; \; \; \; \; J = 0$$

Non-rotational spherically symmetric body of isotropic perfect fluid Stress-Energy tensor metric element functions:
$$T_{\mu \nu} = \left( \begin{array}{ccccc} \; & dt & dr & d \theta & d\phi \\ dt & T_{tt} & 0 & 0 & 0 \\ dr & 0 & T_{rr} & 0 & 0 \\ d\theta & 0 & 0 & T_{\theta \theta} & 0 \\ d\phi & 0 & 0 & 0 & T_{\phi \phi} \end{array} \right) \; \; \; \; \; \; J = 0$$

If the metric has rotation $(J \neq 0)$ and the Einstein tensor metric element functions become non-zero for $g_{t \phi}$, do the Stress-Energy tensors also become non-zero for the corresponding Stress-Energy tensors $T_{t \phi}$?

The Einstein Field Equation does not relate the metric tensor to the stress-energy tensor. It relates the Einstein tensor to the stress-energy tensor. The Wikipedia page describes (briefly) what the Einstein tensor is.

I could not parse your post well enough to give you a good answer, OP, but it seems, like Peter is interpreting, that you think there is a direct relationship between the non-zero members of the metric tensor with the non-zero members of the stress-energy tensor. This is very false, since, for example, in a Schwarzschild space-time all members of the stress-energy tensor are 0 everywhere (except at the singularity) and yet the metric tensor is non-zero.

Also, it is possible to get off-diagonal terms in the Einstein tensor even if the metric tensor is diagonal.
