fix: remove redundant lookup for "audio" voice in PollinationsAI.py and fix key reference in OpenaiTemplate.py

- Removed the line retrieving "voice" from "audio" key inside the PollinationsAI.py file
- Changed the condition in OpenaiTemplate.py from checking "choices" in data to "choices" in data before accessing data["choices"][0] in OpenaiTemplate.py
