League of Angels 2.Are they allowed to use league of legends Talons skill icon for commercial use?

When i'm watching youtube there is a commercial at the right top corner where i can see Talons spell icons used as a commercial in League of Angels 2.Are they even allowed to do that?It doesn't seem legal from my point of view.Can someone verify that.Also it has the design identical to league of legends.
