Questions

Is there a KiCad symbol and footprint for the LM139AD?

Yes. The symbol is Operational Amplifiers:LM139 and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM139AD?

SOIC-14, with 14 pins. Its footprint is drawn on this page.

Where is the LM139AD datasheet?

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

Where can I order the LM139AD?

JLCPCB lists it as part C139364, with 2,791 in stock; the sellers' links on this page open their listings.

What can replace the LM139AD?

Parts like it in the library: the LM339D by Texas Instruments, the LM339DT by STMicroelectronics, the LM239D by Texas Instruments and the LM339 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
