Did I create a new breed on accident???

Totally predictable that you would get black with a lavender and a white mating.
Both are recessive genes and lavender is a dilution of black. Without the recessive white having another copy the chicks default back to black because there was also not another copy of lavender.

Crosses often give unexpected colours. I had a lavender (light greyish) hen and a pile (mostly white ) rooster. The 2 chicks I got where black.

If you want to learn more about mixing chicken genes have a look on chickenjungle. http://kippenjungle.nl/chickencalculator.html

This is not a new breed.

For a new-by that outcome , without investigating the chicken calculator/jungle or similar, it would have been unexpected.

This is why I enjoy having various breeds and colors. It's never predictable what color/pattern you might get! So fun.
