updated llm response parsing action (#3058)

Browse Source 
Sometimes the LLM response (generated code) tends to miss the ending
ticks "```". Therefore causing the text parsing to fail due to not
enough values to unpack.

The 2 extra `_` don't add value and can cause errors. Suggest to simply
update the `_, action, _` to just `action` then with index.

Fixes issue #3057
