Questions

Is there a KiCad symbol and footprint for the SN74LS194AD?

Yes. The symbol is 74xx:74LS194 and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SN74LS194AD?

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

Where is the SN74LS194AD datasheet?

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

Where can I order the SN74LS194AD?

JLCPCB lists it as part C2864014, with 160 in stock; the sellers' links on this page open their listings.

What can replace the SN74LS194AD?

Parts like it in the library: the 74HC165D-JSM by JSMSEMI, the HTC74HC165 by HITENX, the CD74HC595M96 by Texas Instruments and the U74HC165G-S16-R by UTC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
