Questions

Is there a KiCad symbol and footprint for the LM337BT?

Yes. The symbol is EasyEDA_Cloud:LM217LZ-TR and the footprint EasyEDA_Cloud:TO-220-3_L10.0-W4.5-P2.54-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM337BT?

TO-220AB, with 3 pins. Its footprint is drawn on this page.

Where is the LM337BT datasheet?

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

Where can I order the LM337BT?

JLCPCB lists it as part C74415, with 20,247 in stock; the sellers' links on this page open their listings.

What can replace the LM337BT?

Parts like it in the library: the CJ7809 by Jiangsu Changjing Electronics Technology (CJ), the LM1086T-5.0 by HGSEMI, the L7805ABV-DG by STMicroelectronics and the L7905ACV by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
