Yes, it is possible to get a Lv. 2 Espeon. Because Eevee evolves by happiness during day-time, you can max out its happiness level so that it will be able to evolve, than level it once so that it will be able to evolve into Espeon properly.
In this case, somebody got a brand new egg at Lv. 1 and levelled it once so you have a Lv. 2 Espeon.
