Is there a KiCad symbol and footprint for the LM321SN3?
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 LM321SN3?
TSOP-5-1.5mm, with 5 pins. Its footprint is drawn on this page.
Where is the LM321SN3 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the LM321SN3?
JLCPCB lists it as part C457686, with 11,213 in stock; the sellers' links on this page open their listings.
What can replace the LM321SN3?
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.
