Questions

Is there a KiCad symbol and footprint for the SN74LS20NS?

Yes. The symbol is EasyEDA_Cloud:SN74LS21N(XBLW) and the footprint EasyEDA_Cloud:SOIC-14_L10.0-W5.5-P1.27-LS7.8-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

Where is the SN74LS20NS datasheet?

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

Where can I order the SN74LS20NS?

JLCPCB lists it as part C5901032, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SN74LS20NS?

Parts like it in the library: the CD4078BNSR by Texas Instruments, the SN74LS20NSR by Texas Instruments, the SN74HC20NSR by Texas Instruments and the SN74HC21NSR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
