Questions

Is there a KiCad symbol and footprint for the LM3445MM?

Yes. The symbol is EasyEDA_Cloud:LM3445MMX and the footprint EasyEDA_Cloud:VSSOP-10_L3.0-W3.0-P0.50-LS4.9-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM3445MM?

VSSOP-10-0.5mm, with 10 pins. Its footprint is drawn on this page.

Where is the LM3445MM datasheet?

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

Where can I order the LM3445MM?

JLCPCB lists it as part C560971, with 34 in stock; the sellers' links on this page open their listings.

What can replace the LM3445MM?

Parts like it in the library: the LM3445MMX/NOPB by Texas Instruments, the LM3444MM by Texas Instruments and the LM3444MMX by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
