SerperDevTool doesn't work without OpenAI

[varskann]

Reproducing the example https://docs.crewai.com/core-concepts/Tasks/#creating-a-task-with-tools

The code works fine when used with OpenAI models, but not when trying to use Llamma2 with Ollama

Code Snipped to Load Llama2:

from langchain_community.llms import Ollama

# To Load Local models through Ollama
llm_llama = Ollama(model="llama2")

research_agent = Agent(
    role='Researcher',
    goal='Find and summarize the latest AI news',
    backstory="""You're a researcher at a large company.
    You're responsible for analyzing data and providing insights
    to the business.""",
    verbose=False,
    llm=llm_llama
)

Even SerperDev fails to fetch news while using Llama2 model:
