I think to some extent it's possible to reduce cognitive load even on these simpler actions just because you have to see less unrelated data on what you asked about. I say this as someone who doesn't really use LLM integrations.
And these type of requests consume very little tokens in comparison to almost any programming work.
But asking yourself "can I trust this information?" is the baseline amount of cognitive load added to the interaction.
Depending on the level of trust or importance of the decision this may already be a fairly high bar to clear before being able to claim any overall reductions in the interactions itself.
