You may do this in your request:

public function rules()
{
   $rules = [
          'voucher_debt' => ['required', 'array', 'min:1'],
          'voucher_debt.*' => ['nullable', 'numeric', 'min:0.001'],
          'voucher_credit' => ['required', 'array', 'min:1'],
          'voucher_credit.*' => ['nullable', 'numeric' ,'min:0.001'],
   ];

   if (array_sum($this->get('voucher_debt')) - array_sum($this->get('voucher_debt')) == 0) {
       throw new ConflictHttpException('YOUR_MESSAGE');
   }
}

Or you can make your custom validation rule and add to voucher_debt key
