    <Question :title="question.title" :options="question.options" :name="question.id" :visible="question.visible" @opUpdate="opHandle"/>
  </li>  
</ul>

It would suffice to remove the hyphen and use a template literal:

<ul>
    <li
      v-for="(question, i) in questions"
      :key="i" v-show="question.visible"
      :style="{ paddingLeft: `${question.level}rem` }"
    >
        <Question
          @opUpdate="opHandle"
          :title="question.title"
          :options="question.options"
          :name="question.id"
          :visible="question.visible"
        />
    </li>
</ul>

Additional: you can also use v-bind to pass object items to props that have the same name.

<Question
  @opUpdate="opHandle"
  v-bind="question"  // takes care of `title`, `options` and `visible`
  :name="question.id"
/>

You should wrap that property by quotes '' :

:style="{'padding-left': `question.level`rem}">
