Questions

Is there a KiCad symbol and footprint for the TM7780?

Yes. The symbol is EasyEDA_Cloud:TM7780 and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TM7780?

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

Where is the TM7780 datasheet?

TM publishes it: the Datasheet link on this page opens it.

Where can I order the TM7780?

JLCPCB lists it as part C5174545, with 4 in stock; the sellers' links on this page open their listings.

What can replace the TM7780?

Parts like it in the library: the HLW8032 by Hiliwei Tech, the HLW8012 by Hiliwei Tech, the CSE7759-SOP8 by CHIPSEA and the HLW8110 by Hiliwei Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
