[FEATURE] Integrate OpenRouter integration via sub-entries integration?

[Hedda]

Feature Description

Home Assistant 2025.8 Beta release (2025.8.0 will be released in two days) has new OpenRouter integration, wondering if this custom component could use it via integration sub-entries (see separate request #18 ) so that users to not need to login to it separately via this custom component?
