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

Some of the text on this game's Steam store page and promotional materials was drafted with the help of generative AI tools and then reviewed and edited by the developer. Some of the game's source code was also written with the assistance of generative AI tools and then reviewed, tested, and edited by the developer. All player-facing content within the game itself including artwork, music and sound, team and player names, and in-game text was created by the developer without the use of generative AI. The game does not generate any content using AI while you play, and it does not connect to any external AI services.

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.
