Calculate the cost of a given completion call fot GPT-3.5-turbo, llama2, any litellm supported llm.
Parameters:

model (str): Optional. The name of the language model used in the completion calls
prompt (str): Optional. The input prompt passed to the llm
completion (str): Optional. The output completion text from the llm
total_time (float): Optional. (Only used for Replicate LLMs) The total time used for the request in seconds
Returns:
float: The cost in USD dollars for the completion based on the provided parameters.
Note:
- If completion_response is provided, the function extracts token information and the model name from it.
- If completion_response is not provided, the function calculates token counts based on the model and input text.
- The cost is calculated based on the model, prompt tokens, and completion tokens.
- For certain models containing "togethercomputer" in the name, prices are based on the model size.
- For Replicate models, the cost is calculated based on the total time used for the request.
