The developers describe how their game uses AI generated content like this:

Used AI to generate concept ideas and take care of tedious tasks to speed up preproduction. All assets, including store images and thumbnails, are NOT AI generated. Images provided to us by Patron supporters may or may not have been created using artificial intelligence.

Required on Steam store pages since 2024. It covers content that ships in the game, on its store page or in its marketing — Valve does not require a disclosure for AI tools used during development, so this says nothing either way about how the game was made. Check it on Steam.
