Questions

Is there a KiCad symbol and footprint for the LM20144MH?

Yes. The symbol is EasyEDA_Cloud:LM20143MHX_NOPB and the footprint EasyEDA_Cloud:TSSOP-16_L5.0-W4.4-P0.65-LS6.4-BL-EP3.3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM20144MH?

HTSSOP-16-EP, with 17 pins. Its footprint is drawn on this page.

Where is the LM20144MH datasheet?

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

Where can I order the LM20144MH?

JLCPCB lists it as part C1356218, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM20144MH?

Parts like it in the library: the LM20154MHX by Texas Instruments, the LM2854MHX-500 by Texas Instruments, the LM20145MHX by Texas Instruments and the LM20136MHX by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
