Is there a KiCad symbol and footprint for the LM26003MH?

Yes. The symbol is EasyEDA_Cloud:LM26003QMHX_NOPB and the footprint EasyEDA_Cloud:HTSSOP-20_L6.5-W4.4-P0.65-LS6.4-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM26003MH?

HTSSOP-20-EP, with 21 pins. Its footprint is drawn on this page.

Where is the LM26003MH datasheet?

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

Where can I order the LM26003MH?

JLCPCB lists it as part C1355760, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM26003MH?

Parts like it in the library: the LM20343MH by Texas Instruments, the LM21215AMHE-1 by Texas Instruments, the TPS56920PWP by Texas Instruments and the LM21215MHE by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
