LLM-Comparator-UI-Node

KI.NRW has asked if it would be possible to create LLM-Comparator-UI-Node that could be used to send the same user prompt to the connected LLM-Nodes and display the different results

and the comparator-ui could look like this

we might need to extend the unified-llm-protobuf to have a llm-model-name in the model reponse?
