I want to allow all github org in aws iam role trusted entity (OIDC)

AWS does not provide the capability to assume a role from ANY GitHub organization. Even if you create a trusted policy like this:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Federated": "arn:aws:iam::50********80:oidc-provider/token.actions.githubusercontent.com"
            },
            "Action": "sts:AssumeRoleWithWebIdentity",
            "Condition": {
                "StringEquals": {
                    "token.actions.githubusercontent.com:sub": "repo:*",
                    "token.actions.githubusercontent.com:aud": "sts.amazonaws.com"
                }
            }
        }
    ]
}

GitHub workflow will not be able to assume such a role.

You can create a Free GitHub organization and use it
