There are some relevant tools for this, such as https://thanks.dev. While it doesn't work as a usage-based billing, at least it provides a way to fund all dependencies.

However, the issue is that most organizations relying on OSS are not tech companies. They mainly have no clue about OSS sustainability (e.g., airports and hospitals) and are unlikely to ever fund their own software supply chains, unfortunately. That's why there should be a data-driven index to address the global OSS supply chain, not only any particular ones.
