Questions

Is there a KiCad symbol and footprint for the ATTINY20-MMH?

Yes. The symbol is MCU_Microchip_ATtiny:ATtiny20-MM and the footprint Package_DFN_QFN:QFN-20-1EP_3x3mm_P0.45mm_EP1.6x1.6mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATTINY20-MMH?

VQFN-20(3x3), with 21 pins. Its footprint is drawn on this page.

Where is the ATTINY20-MMH datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the ATTINY20-MMH?

JLCPCB lists it as part C145598, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ATTINY20-MMH?

Parts like it in the library: the ATTINY44A-MMH by Microchip Technology, the ATTINY40-MMHR by Microchip Technology, the ATTINY841-MMH by Microchip Technology and the ATTINY441-MMH by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
