Questions

Is there a KiCad symbol and footprint for the FT2128P?

Yes. The symbol is EasyEDA_Cloud:FT2128P 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 FT2128P?

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

Where is the FT2128P datasheet?

SG Micro publishes it: the Datasheet link on this page opens it.

Where can I order the FT2128P?

JLCPCB lists it as part C5153084, with 0 in stock; the sellers' links on this page open their listings.

What can replace the FT2128P?

Parts like it in the library: the TC8002D by FM, the LM833D by onsemi, the LM4871MX by Texas Instruments and the FM8002E by Shenzhen Fuman Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
