trait DialogTrait
{
    protected function confirm(InputInterface $input, OutputInterface $output): bool
    {
        $helper = $this->getHelper('question');

It seems like getHelper() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        $question = new ConfirmationQuestion('Are you sure? [y\N]: ', false);
        return $helper->ask($input, $output, $question);
    }
}
