Python Issue while login in to ajax website with a checkbox of terms and conditions

I am getting this issue while loggin in to a ajax website, the issue is while login in it requires username, password and checkbox i agree with terms and conditions. I have tried login in with only username and password but it returns an error that you must agree with terms and conditions Can any one help me with this?

from bs4 import BeautifulSoup as bs
import requests
import csv
import urllib.request

URL = 'https://www.somesite.com/Login'
LOGIN_ROUTE = 'https://www.somesite.com/Login/Check'
user_agent = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.3'
HEADERS={'User-Agent':user_agent} 
s = requests.session()

csrf_token = s.get(LOGIN_ROUTE).cookies['__RequestVerificationToken']
print("\ncsrf_token " +csrf_token)

login_payload = {
        'Login.UserName': 'username',
        'Login.Password': 'password', 
        '__RequestVerificationToken': csrf_token
        }

login_req = s.post(LOGIN_ROUTE, headers=HEADERS, data=login_payload)

if login_req.status_code==200:
  print(str(login_req.status_code) + " login successful\n") #if successful, 200 will be returned
else:
  print(str(login_req.status_code) + " login unsuccessful")

cookies = login_req.cookies
soup = bs(login_req.text, 'html.parser')
print("Parse text begins here")
print(soup)

the returned page is :
