Korea. IL-2 Series

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

Generative technologies are used in Korea. IL-2 Series as production tools for selected types of content: in-game radio communications, pilot portraits and images used in Career mode. Radio communications use text-to-speech technology based on voice recordings made by our team and voice actors under the relevant agreements. Pilot portraits and Career mode images are created with AI-assisted workflows based on our own assets, in-game screenshots, models, and historical references, then manually reviewed and refined by our artists. Generative AI is not used as a replacement for creative direction. All such content is curated, checked, and finalized by the development team.

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.
