I was wondering if it was a way to 'flaunt' his avoidance of LLMs. Could be in future genuine human conversation will be so rare that we will seize upon mistakes and typos like finding a shiny jewel in mud.
(But then I saw he used the formation - 'Honestly?' which made me think he WAS using LLMs!)
To flaunt:
> display (something) ostentatiously, especially in order to provoke envy or admiration or to show defiance.
To flout:
> openly disregard (a rule, law, or convention).
(I'm also a non-native speaker)
