Making that feature illegal may backfire spectacularly across the whole IT sector. What Apple does is it inputs voice data into an AI program and that outputs some transformed output. If a court would rule that output in any way matches the input (to be classified as a "record") then the whole ethics principle of stealing other people's data and funneling it through AI to make it company's own, would be at risk.

I imagine no single spineless impotent modern court would risk a wrath of our new benevolent AI overlords calling them all criminals they really are.
