Questions

Is there a KiCad symbol and footprint for the LM317BT?

Yes. The symbol is EasyEDA_Pro:LM317BTG and the footprint EasyEDA_Pro:to-220-3_l10.0-w4.5-p2.54-l, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM317BT?

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

Where is the LM317BT datasheet?

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

Where can I order the LM317BT?

JLCPCB lists it as part C14502, with 6,457 in stock; the sellers' links on this page open their listings.

What can replace the LM317BT?

Parts like it in the library: the L7805ABV by STMicroelectronics, the L7812CV-DG by STMicroelectronics, the L7912CV-DG by STMicroelectronics and the L7815CV-DG by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
