Seems like all normal english words could risk the same, so would using short but random strings be even better?

Actually to me it sounds it could be benchmarked if this kind of effect exists in the first place.

Best option would be reasoning + clear system instructions + constrained output. That is, if you have to use a chat model. Which works well enough to be sure, but hey I haven't tried raising millions of dollars when I did that 3 years ago. But perhaps I was the stupid one.
