Questions

Is there a KiCad symbol and footprint for the LM339QT?

Yes. The symbol is EasyEDA_Cloud:TSX339IQ4T and the footprint EasyEDA_Cloud:TQFN-16_L3.0-W3.0-P0.50-BL-EP1.7, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM339QT?

TQFN-16-EP(3x3), with 17 pins. Its footprint is drawn on this page.

Where is the LM339QT datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the LM339QT?

JLCPCB lists it as part C2926946, with 10,588 in stock; the sellers' links on this page open their listings.

What can replace the LM339QT?

Parts like it in the library: the LM339LVRTE by Texas Instruments and the LM2901BIRTE by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
