Is there a KiCad symbol and footprint for the AD9281ARS?

Yes. The symbol is EasyEDA_Cloud:AD9281ARS and the footprint Package_SO:SSOP-28_5.3x10.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AD9281ARS?

SSOP-28-208mil, with 28 pins. Its footprint is drawn on this page.

Where is the AD9281ARS datasheet?

Analog Devices publishes it: the Datasheet link on this page opens it.

Where can I order the AD9281ARS?

JLCPCB lists it as part C653443, with 0 in stock; the sellers' links on this page open their listings.

What can replace the AD9281ARS?

Parts like it in the library: the AD9826KRSZRL by Analog Devices, the MS9280 by Hangzhou Ruimeng Tech, the HT9201ARSZ by HTCSEMI and the ADS1241E/1K by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
