Add a 1 minute retry if rate limitted so execution can run to completion

[MinhNgyuen]

Problem: Execution can grind to a halt midway through if a rate limit is encountered and progress (search and llm usage) will be lost

Solution: If the rate limit is encountered, go to sleep for 1 minute until the tokens per minute rate limit is refreshed.

Testing:

• Ran this code
• Encountered the rate limit 5+ times
• Verified with the print statement that execution went to sleep for 1 minute for the rate limit
• Execution progressed as normal after the sleep
