Re:N8n vs. node-red, which to use for AI workloads

You can navigate a graph just fine if you set up flows to iterate through it, just like state machines (there are a few patterns to do that in Node-RED with branching and iteration). It’s perfectly possible.
However, there is something you mention that I think is important - dashboard 2 is still missing critical functionality—for instance, I cannot set it up as the “/“ (homepage) URL in an instance (there’s a lingering bug for that for around a year now) and it is still far from being as well integrated as the original.
As a hack, I have got LangGraph working inside of a node-red flow. I will write it up as a medium article in the next few days, as it might be of help to others. It's very codey.
I think production engineers will have to master the Langchain ecosystem, when we creating mission critical AI based systems. I think node-red has good nodes in place to record decisions and data as part of an AI ethics program.
Flowise have a good set of nodes around langchain, but I bet it was a massive and expensive undertaking to build.
Also Dashboard 2 is something n8n is sorely missing and is needed to monotor live systems.
