Sure, just on the training front, building and maintaining a broad corpus of properly managed training data with metadata that provides attribution (for example, content that is known to be human generated instead of model generated, what the source of data is for datasets such as weather data, census data, etc), and that also captures any licensing encumbrance so that consumers of the training data can be confident in their ability to use it without risk of legal challenge.
Much of this is already available to private sector entities, but having a publicly funded organization responsible for curating and publishing this would enable new entrants to quickly and easily get a foundation without having to scrape the internet again, especially given how rapidly model generated content is being published.
