Is there a pre-built OpenWrt package or script for integrating with Cloudflare Speed Test?

There isn't a widely maintained, official pre-built package specifically for integrating with Cloudflare Speed Test in OpenWrt. However, you can find community-developed scripts and tutorials on platforms like GitHub and the OpenWrt forums. These scripts may require modification to suit your specific needs and OpenWrt version. Be cautious when using third-party scripts and thoroughly review the code before deploying it on your network. It's generally recommended to understand the script's functionality and security implications before using it.
