[BUG] LLM().call() doesn't work with Tools

Description

LLM().call() doesn't work with Tools

Steps to Reproduce

code

Expected behavior

I want to use the LLM() class without Agent() for more control over the "messages" (lower level).

Screenshots/Code snippets

import crewai as c
import crewai.flow as cf
import crewai_tools as ct
import logging
from pathlib import Path

logging.basicConfig(level=logging.DEBUG)

llm = c.LLM(model="ollama/my", base_url="http://127.0.0.1:8080")
print(c.__version__)

ROOT = Path(Path(__file__).parent, "_temp").resolve()
ROOT.mkdir(parents=True, exist_ok=True)
fwriter = ct.FileWriterTool(base_dir=str(ROOT))
freader = ct.FileReadTool(base_dir=str(ROOT))

print(llm.call(
    messages=[{"role":"user","content":"Who are you?"}],
    tools=[fwriter, freader],
))
