I just had a brief look and it seems to me this would need to be reworked from scratch, since we implemented langchain support by now, just without the iast support.

@uurien I am closing this for now while I believe it would be valuable to get the PR again to support iast with llm. I just think it would likely be best to start with a new PR.
