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

AI-generated content is used in this product. The store page capsule artwork was created using an AI image generation tool. Portions of the store page description text were drafted with the assistance of an AI writing tool and reviewed/edited by the developer.

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.
