Remove deprecated chain

[Sachin-Bhat]

Hey @eyurtsev

Here are the listed changes:

• kor/extraction/api.py: Removed deprecated LLMChain and arun and instead replaced them with RunnableSequence and ainvoke respectively, Added set_verbose context to set the verbosity within the context of a function to mimic the old chain_kwargs verbose functionality.
• tests/extraction/test_extraction_with_chain.py: Removed deprecated LLMChain, mimic langchain.verbose with get_verbose()

Please let me know if any changes need to be made. Merging this fixes #305.

Cheers,
Sachin

Awesome, I'll confirm this works and make this a breaking release since .run interface won't be available anymore

Hey @eyurtsev

Are we looking at a new release with this merge?

Cheers,

Yep, but there are a few remaining issues to resolve. I'm updating the documentation right now.

I deprecated verbose functionality, and looking at how to get the prompt out of the chain since we lost that

Maybe langchain.globals.set_verbose(bool) is an avenue to explore within the context of the function?

The context needs to be set at chain run time rather than chain creation time.

The best way to do this with runnables is by passing a callback or langchain_core.globals.set_verbose / set_debug.

Released #311
