Questions

Is there a KiCad symbol and footprint for the DM7474N?

Yes. The symbol is 74xx:74HC74 and the footprint Package_DIP:DIP-14_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the DM7474N?

PDIP-14, with 14 pins. Its footprint is drawn on this page.

Where is the DM7474N datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the DM7474N?

JLCPCB lists it as part C3827260, with 0 in stock; the sellers' links on this page open their listings.

What can replace the DM7474N?

Parts like it in the library: the HEF4027BT by Nexperia, the DM7474M by onsemi and the DM7474MX by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
