Ask the project to offer an EU-hosted endpoint or a self-hosted Docker image, and to publish a clear dataflow diagram showing which inputs, inference steps, logs and backups are stored or processed in Mainland China.

Practically that can be done by provisioning EU clusters with Terraform on AWS eu-west-1 or a European host like Hetzner, using geolocation DNS or Cloudflare load balancing to steer users and pin accounts to a region, while accepting higher costs, more complex CI/CD and subtle GDPR issues around backups and telemetry.
