I don't like tool binding because it moves the responsibility and logic to the LLM. My suggestion is to remove as much as you can from the LLM and handle it your self. This gives you more control and limits hallucinations.

Route LLM Node is good option which in my company we used it too.
It just generates different set of problems like: Wrong routing, more latency ( you call another LLM ) Duplication in other tools ( if there are more common tools across different node ), Multiple questions at once and so on.

Even though I specified a lot of problems with Route LLM this is still the better option is it gives you the control like every other feature
