Questions

Is there a KiCad symbol and footprint for the SN74LS373N?

Yes. The symbol is 74xx:74LS373 and the footprint Package_DIP:DIP-20_W7.62mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SN74LS373N?

DIP-20, with 20 pins. Its footprint is drawn on this page.

Where is the SN74LS373N datasheet?

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

Where can I order the SN74LS373N?

JLCPCB lists it as part C10423, with 77 in stock; the sellers' links on this page open their listings.

What can replace the SN74LS373N?

Parts like it in the library: the SN74HC573AN by Texas Instruments, the SN74HC373N(LX) by lingxingic, the SN74HC373N(XBLW) by XBLW and the SN74LS373N(XBLW) by XBLW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
