Adding LLM knowledge to a Question means that GPT can auto answer the Question. This can be used for List and Boolean questions.
GPT will use the question description and each list value combing them to generate a question for each option.
Once GPT has made a suggestion for each list value it is possible for the user to edit the question.
Here the user can select the provider to be used and also provide some context for GPT to work in via the LLM System Message.
