Is there a KiCad symbol and footprint for the NTE74LS74A?

Yes. The symbol is 74xx:74LS74 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 NTE74LS74A?

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

Where is the NTE74LS74A datasheet?

NTE Electronics publishes it: the Datasheet link on this page opens it.

Where can I order the NTE74LS74A?

JLCPCB lists it as part C6622709, with 0 in stock; the sellers' links on this page open their listings.

What can replace the NTE74LS74A?

Parts like it in the library: the XD74LS74 by XINLUDA, the SN74LS74ANE4 by Texas Instruments, the HD74LS74AP by Renesas Electronics and the CD74HCT175M96 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
