Questions

Is there a KiCad symbol and footprint for the LM321?

Yes. The symbol is Amplifier_Operational:LM321 and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM321?

SOT-23-5L, with 5 pins. Its footprint is drawn on this page.

Where can I order the LM321?

JLCPCB lists it as part C605443, with 4,949 in stock; the sellers' links on this page open their listings.

What can replace the LM321?

Parts like it in the library: the LMV321IDBVR by UMW, the LM321MF by UMW, the TLV9061IDBV by Texas Instruments and the LM321-TR by Gainsil. Check their datasheets: a part that fits the footprint may still differ in its ratings.
