I thought they were talking about the traditional blue links Google search results, not the AI returned results. Then sure -- ChatGPT, Gemini, etc... I put them all in the same bucket as complementary. Interestingtly though, I don't get the AI Overview on mobile, so there I'd have to explicitly go to an LLM focused interface.
I just tried the same search from my mobile phone. I see the same AI generated response.
Real question: Do you think normies distinguish between traditional Google search results and AI Overview? To me, normies use Google to find an answer. They don't care too much where the answer comes from.
