Yes both Modern Agfa/A&O Rodinal and Calbe R09 contain Bromide.

Rodinal works exceptionally well with modern films with a high iodide content like Tmax & Delta 100, so it's possible that a small addition of KI to a Rodinal substitute would help with some older type emulsions, but we'd only be talking somewhere in the region of 0.25g per litre of concentrate
