It's assumed that programs will setup their own NIL deals with athletes if the House settlement is finalized as planned. Most departments are already making anticipatory moves and signing MOUs with recruits now. Third-party collectives and direct sponsorship NIL can continue to co-exist with the new framework.

Also, about getting details of NIL transactions out in the open: there are pending bills in congress right now that include reporting of NIL deals (among other reforms), sanitized of personal information, to provide athletes with a better idea of their fair market value. Agents are now becoming a thing in college sports, and since none of this is well-regulated with little to no uniformity, a lot of kids are expect outrageous numbers and end up signing predatory deals disguised as high-interest loans, or that take a cut of the athletes future pro salary, and who knows what else.
