Chicken_Run

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

During the game's development process, the Generative AI was used as a development aid. AI was used in some game image production and code review and improvement proposals, and all final images and codes included in the game were reviewed, modified, and quality checked by developers. The AI-generated results were not used without review, and verification procedures were performed to ensure that they did not infringe copyright and third-party rights. In addition, AI does not generate content or code in real time during gameplay.

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.
