🔨 refactor(llms.py): extract formatting methods for Azure and Llama fields

This commit extracts the formatting methods for Azure and Llama fields from the `format_field` method to improve readability and maintainability of the code. The `format_azure_field` method formats the fields for Azure, while the `format_llama_field` method formats the fields for Llama. These methods are called conditionally based on the name of the field.
