[Bug] Response Format of json is not working in openai about langchaingo

[devalexandre]

@devalexandre Yes, I was able to achieve it with the following code:

response, err := client.GenerateContent(ctx, content, llms.WithJSONMode())

However, I noticed that there are unused keys for every OpenAI LLM, specifically "openai.WithResponseFormat(responseFormat)", which isn't being utilized. I wanted to report this issue here.

this is not BUG as we have option base but for each LLM, use some options, never use all.

maybe we could return a error if some option aren't used.

ctx := context.Background()

client, err := openai.New(openai.WithModel("gpt-3.5-turbo")))

	content := []llms.MessageContent{
		llms.TextParts(llms.ChatMessageTypeSystem, "You are a company branding design wizard."),
		llms.TextParts(llms.ChatMessageTypeHuman, "What would be a good company name a company that makes colorful socks?"),
	}

//add type in request
	opts := llms.CallOptions{
		JSONMode: true,
	}

	resp, err := client.GenerateContent(ctx, content,opts)

	fmt.Println(resp.Choices)

	for _, message := range resp.Choices {
		fmt.Println(message.Content)
	}

	return err
	``
