those tours really are totally annoying
you could create a server action on users and create a contextual action using the following code

name: Consume All Known Tours

python code:

tour_mod = env["web_tour.tour"]
known_tour_names = set(tour_mod.search([]).mapped('name'))

for user_id in records:
  log_msg = ''
  for tour_name in known_tour_names:
    tour_id = tour_mod.search([('name', '=', tour_name),('user_id', '=', user_id.id)])
    if tour_id:
      log_msg = "{}user {} already consumed tour {}\n".format(log_msg, user_id.name, tour_name)
    else:
      tour_id = tour_mod.sudo().create({'name': tour_name, 'user_id': user_id.id})
      log_msg = "{}consumed tour {} for user {}\n".format(log_msg, tour_name, user_id.name)
  log(log_msg, level='info')

note that this relies on that someone (e.g. the admin through debug and the "disable all tours" on the bug) consumed all tours already.
it will then be applied to all users that are selected when the action is run
it also creates a log entry per user so you can check what it did...
