It would depend on the binding mode - frequently, Many transcription factors recognize the sequence on double-stranded DNA - in RNA, dependent on secondary structure, the local structure may be quite different.
As mentioned above that RNA conformation may be different in space, it may not be feasible to do a sequence prediction as feasible for DNA. It may be possible to do a molecular docking (if structure of TF is available), or you may also try to do a physical binding experiment between the two
