Completely disagree - a lot of non-native speakers have excellent grasp of grammar, precisely because they have learnt the rules. Native speakers rely on stuff sounding right, rather than necessarily knowing the rules. But following grammatical rules rigidly is exactly what I would expect both from a genAI and a non-native speaker (as well as avoiding figurative speech and idioms).

I felt like I wasn’t able to make any decisions were I was happy with the outcome.

That’s generally a consistent theme in the cyberpunk genre. You can’t win and you can’t get out of the game.
