Questions

Is there a KiCad symbol and footprint for the CS3855EO?

Yes. The symbol is EasyEDA_Cloud:CS3855EO and the footprint EasyEDA_Cloud:HTSSOP-28_L9.7-W4.4-P0.65-LS6.4-BL-EP5.5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CS3855EO?

HTSSOP28, with 29 pins. Its footprint is drawn on this page.

Where is the CS3855EO datasheet?

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

Where can I order the CS3855EO?

JLCPCB lists it as part C7421635, with 0 in stock; the sellers' links on this page open their listings.

What can replace the CS3855EO?

Parts like it in the library: the BD5444EFV-E2 by ROHM Semiconductor, the LM4817MHX by Texas Instruments, the LM4841MH by Texas Instruments and the HT3110DRETZ by HTCSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
