Yes, while citing an LLM in the same way is probably not as useful.
"I googled this" is only helpful when the statistic or fact they looked up was correct and well-sourced. When it's a reddit comment, you derail into a new argument about strength of sources.
The LLM skips a step, and gets you right to the "unusable source" argument.
I agree. Telling I googled this and someone has this opinion is pretty useless. Be that someone a LLM or random poster on internet.
Still, I will fight that someone actually doing the leg work even by search engine and reasonable evaluation on a few sources is often quite valuable contribution. Sometimes even if it is done to discredit someone else.
