Feature request

I'm trying to use Ollama instead of ChatAnthropic in this tutorial "https://langchain-ai.github.io/langgraph/tutorials/introduction/#requirements" but it seems is not working with llm object created with Ollama

llm = Ollama(
model="llama3"
)

tool = TavilySearchResults(max_results=2)
tools = [tool]
tool.invoke("What's weather in Amherst?")
llm_with_tools = llm.bind_tools(tools)

Motivation

I'm trying to use Ollama (local llm) instead of an API call from Anthropic and integrate search.

Proposal (If applicable)

We can implement bind_tools for Ollama objects. Similar issue -> "#21907"

use ChatOllama instead
from langchain_ollama import ChatOllama
