Is there a KiCad symbol and footprint for the SN74LS166AN3?

Yes. The symbol is 74xx:74LS166 and the footprint Package_DIP:DIP-16_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 SN74LS166AN3?

DIP-16, with 16 pins. Its footprint is drawn on this page.

Where is the SN74LS166AN3 datasheet?

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

Where can I order the SN74LS166AN3?

JLCPCB lists it as part C3301237, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SN74LS166AN3?

Parts like it in the library: the SN74HC595N(XBLW) by XBLW, the SN74HC595NED-GMIC by GREENMICRO, the SN74LS165AN(LX) by lingxingic and the AIP74HC165DA16.TB by Wuxi I-core Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
