No response and exit code is zero for PROHIBITED_CONTENT

The command like llm -m gemini-2.0-flash "prompt" -f "file.txt" returned no response nor any indication of a failure. llm version is 0.25

In responses table response field is empty. response_json is below:

{
    "promptFeedback": {
        "blockReason": "PROHIBITED_CONTENT"
    },
    "usageMetadata": {
        "promptTokenCount": 9311,
        "totalTokenCount": 9311,
        "promptTokensDetails": [
            {
                "modality": "TEXT",
                "tokenCount": 9311
            }
        ]
    },
    "modelVersion": "gemini-2.0-flash"
}

Additionally, these fields are null:

• input_tokens
• output_tokens
• token_details

The quickest fix could be just output the json to stdout, so a user have a clue of what's going on.
