Delete multiple Layers by selecting multiple object?

Hi Designers,

I'm going to connect my AI file to After effect.

So I had to create lots of layers in order to edit them seperatly in After effects.

But it seems like my amount of layers are too large because AE always crashes (not responding -> Force quit)

So I wanna break some stuff down in multiple AI files, but I don't wanna go and select every layer and delete it.

That would take too much time.

Is there a way to select the multiple objects in Illustrator and delete that but also its layer its in?

Thank you!
