This reminds me of one of my mega tickets issued by my work's travel agency - 14 segments on 7 carriers across 2 alliances with 3 ticket numbers, all plated on 001 (AA) because they operated the first segment on this trip.

I think I have asked you this before, I just would like to better understand who is responsible here.
Back on topic - the plating carrier (DL) does nothing more than holding the funds and disburse them to each respective airlines involved in the trip. The ticket issuer (in this case, Expedia) is responsible for any ticketing anomalies. If the ticket was purchased and issued by Delta and not through a travel agency, then Delta is responsible for repairing the ticket.
The typical issue with a ticket mismatch is that there is no electronic ticket associated with the PNR, causing the check-in issue. The remedy at the airport would be trying to insert the e-ticket number into the PNR, or even physically print out the "ticket" as a paper ticket to attach to the boarding pass. In this case, it appears that at some point there was a schedule change that caused flight changes, and the ticket was not properly revalidated and/or reissued to include all segments. Therefore, it's not something the KL agent can fix on the spot, and must go back to the ticket issuer for remedy. The KL agent probably assumed that OP purchased the ticket from DL directly, hence asking them to call DL, instead of the travel agency.
If this were an IRROP, then the operating carrier (KL) is responsible for delivering the passenger to the final destination.
With that said, sounds like DL is offering a customer gesture, which is a net-positive outcome.
