Questions

Is there a KiCad symbol and footprint for the 74LS374PC?

Yes. The symbol is 74xx:74LS374 and the footprint Package_DIP:DIP-20_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 74LS374PC?

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

Where is the 74LS374PC datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the 74LS374PC?

JLCPCB lists it as part C3827458, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 74LS374PC?

Parts like it in the library: the DM74ALS273N by onsemi, the DM74ALS374N by onsemi, the MC74HC273AN by onsemi and the MM74HC374AN by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
