Questions

Is there a KiCad symbol and footprint for the LR321?

Yes. 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 LR321?

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

Where is the LR321 datasheet?

Leshan Radio (LRC) publishes it: the Datasheet link on this page opens it.

Where can I order the LR321?

JLCPCB lists it as part C2936724, with 2,363 in stock; the sellers' links on this page open their listings.

What can replace the LR321?

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.
