Is the purpose of the goop they slather around the bead of a tubeless
tire to lubricate during installation, to help seal the tire rim
interface, or both? I have a freebee dolly on which one of the tire has
a very very slow leak at the interface. What is this goop? The local
auto parts store was of no help.

Murphy's soap. Lubricant only; no sealing properties.

For a one time deal, mix some stout dish washing soap solution.

DO NOT use diesel or any petroleum product.
