Questions

Is there a KiCad symbol and footprint for the SN74LS122N?

Yes. The symbol is EasyEDA_Cloud:SN74LS122NS 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 SN74LS122N?

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

Where is the SN74LS122N datasheet?

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

Where can I order the SN74LS122N?

JLCPCB lists it as part C1522780, with 88 in stock; the sellers' links on this page open their listings.

What can replace the SN74LS122N?

Parts like it in the library: the CD4047BE by Texas Instruments, the SN74121N by Texas Instruments, the CD4047BEE4 by Texas Instruments and the CD4047BEG4 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
