Yes. The symbol is agg-kicad:AD8551 and the footprint Package_SO:MSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
MSOP-8, with 8 pins. Its footprint is drawn on this page.
Analog Devices publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C1347554, with 2 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the GS8552-MR by Gainsil, the RS8552XM by Jiangsu RUNIC Tech, the TP5552-VR by 3PEAK and the CBM8629AMS8 by Corebai Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
