Questions

Is there a KiCad symbol and footprint for the LM2940G-12-AA3-R?

Yes. the footprint EasyEDA_Cloud:SOT-223-3_L6.5-W3.4-P2.30-LS7.0-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2940G-12-AA3-R?

SOT-223-3, with 4 pins. Its footprint is drawn on this page.

Where is the LM2940G-12-AA3-R datasheet?

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

Where can I order the LM2940G-12-AA3-R?

JLCPCB lists it as part C127023, with 4 in stock; the sellers' links on this page open their listings.

What can replace the LM2940G-12-AA3-R?

Parts like it in the library: the CJ7812 by Jiangsu Changjing Electronics Technology (CJ), the MC7912BT by onsemi, the L7812CV(XBLW) by XBLW and the L7812CV-JSM by JSMSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
