Reporting $0 earnings/expenses for LLC? (with a few caveats...)

I formed an LLC thinking I might use it for a small amount of income I received in 2023. I ultimately decided to simply bring in that income as a sole proprietor (through my own bank account, etc). It was only few thousand dollars that I reported as business income on schedule C, and it's almost all eaten up by expenses. I don't plan to remain in the field or do more work of this nature. Since I never used the LLC, I also plan to dissolve it this year (2024). 

However, I've read that all entities must file a federal tax return whether or not they have any income or expenses to report. How do I report income for my LLC? It's registered in my name, but the LLC company name is a creative title I chose for the industry I thought I'd be using it for. Does my LLC need a totally separate tax return with its own name, where I report $0 income and $0 expenses?
