Questions

Is there a KiCad symbol and footprint for the LM3621M?

Yes. The symbol is EasyEDA_Cloud:LM3621M and the footprint Package_SO:SO-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM3621M?

SOIC-16, with 16 pins. Its footprint is drawn on this page.

Where is the LM3621M datasheet?

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

Where can I order the LM3621M?

JLCPCB lists it as part C3681483, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM3621M?

Parts like it in the library: the ADP3801AR-REEL by Analog Devices, the DS2712ZB+T by Analog Devices, the LT1579CS#PBF by Analog Devices and the LT1579CS#TRPBF by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
