Questions

Is there a KiCad symbol and footprint for the CS3815EO?

Yes. The symbol is EasyEDA_Cloud:CS3815EO_C7421636 and the footprint EasyEDA_Cloud:TSSOP-28_L9.7-W4.4-P0.65-LS6.4-BL-EP6.2-1, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CS3815EO?

HTSSOP-28, with 29 pins. Its footprint is drawn on this page.

Where is the CS3815EO datasheet?

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

Where can I order the CS3815EO?

JLCPCB lists it as part C7421636, with 257 in stock; the sellers' links on this page open their listings.

What can replace the CS3815EO?

Parts like it in the library: the CS3817BEO by CRMICRO, the CS3818EO by CRMICRO, the CS3830EO by CRMICRO and the CS3817EO by CRMICRO. Check their datasheets: a part that fits the footprint may still differ in its ratings.
