 **Cost Attribution Flow:**
 1. LLM response returns to `utils.py` wrapper after `litellm.acompletion()` completes
-2. `update_response_metadata()` (`llm_response_utils/response_metadata.py`) is called
-3. `logging_obj._response_cost_calculator()` (`litellm_logging.py`) calculates cost via `litellm.completion_cost()` (`cost_calculator.py`)
+2. `update_response_metadata()` (`litellm_core_utils/llm_response_utils/response_metadata.py`) is called
+3. `logging_obj._response_cost_calculator()` (`litellm_core_utils/litellm_logging.py`) calculates cost via `litellm.completion_cost()` (`cost_calculator.py`)
 4. Cost is stored in `response._hidden_params["response_cost"]`
 5. `proxy/common_request_processing.py` extracts cost from `hidden_params` and adds to response headers (`x-litellm-response-cost`)
 6. `logging_obj.async_success_handler()` triggers callbacks including `_ProxyDBLogger.async_log_success_event()`
