It was not simply left out. The omission of flow control and retransmission at L2 was deliberate, and reflects IP's need to run on links that by their nature cannot support transmission state. Had the RFC 791 authors been willing to limit themselves to a known set of link layer protocols we would not today have any Internet at all.
