You can only do this using a program. Use the AWS SDK, list all ARNs, loop through them all and call the tag resource api on each of them. This is how you tag a bunch of tables in Python:

    session = boto3.Session(profile_name="my-region")
    client = session.client('dynamodb')

    # Get all DDB tables
    tables = client.list_tables()
    
    # Loop through tables
    for table in tables['TableNames']:
        print(f'Tagging table: {table}')
        client.tag_resource(ResourceArn=f'arn:aws:dynamodb:us-east-1:xxx:table/{table}',Tags=[{'Key':'my_tag','Value':'my_tag_value'}])
