In continuous_eval/metrics/generation/text/llm_based.py, line 39, the full model parameters are not being passed to the LLMBasedContextCoverage class. This means that the code defaults to calling OpenAI API even if another LLM is passed as self.model

Changes requied

AS-IS:
context_coverage = LLMBasedContextCoverage(use_few_shot=self.use_few_shot)

TO-BE:

context_coverage = LLMBasedContextCoverage(model=self._llm, use_few_shot=self.use_few_shot)
