Questions

Is there a KiCad symbol and footprint for the DMC4050SSD?

Yes. The symbol is LibrePCB_Diodes_Incorporated:DMC4050SSD[Q] and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the DMC4050SSD?

SO-8, with 8 pins. Its footprint is drawn on this page.

Where is the DMC4050SSD datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the DMC4050SSD?

JLCPCB lists it as part C444479, with 0 in stock; the sellers' links on this page open their listings.

What can replace the DMC4050SSD?

Parts like it in the library: the AO4485 by Alpha & Omega Semiconductor, the AO4264E by Alpha & Omega Semiconductor, the SI9407BDY by Vishay Intertechnology and the AO4421 by Alpha & Omega Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the DMC4050SSD?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
