The provided code snippet has some small improvements but can be optimized further:

1. Simplify Tooltip Rendering: The conditional rendering of TooltipLabel and <span> can be simplified using Vue's ternary operator for better readability.

<template #label>
  <div class="flex-between">
    <div>
      {{ item.label.attrs.tooltip ? 
          <TooltipLabel label={item.label.label} tooltip={item.label.attrs.tooltip} /> :
          <span>{item.label.label}</span> }}
      <span v-if="item.required" class="color-danger">*</span>
    </div>
    <el-select

2. Avoid Duplicated Code: There is repetition in the template for handling tooltips across different elements. If you have multiple similar components with labels that might contain tooltips, consider creating a reusable component.

<div class="tooltip-container">
  <TooltipLabel v-if="hasTooltip(label)" :label="$t('common.field_label')" :tooltip="label.attrs.tooltip"/>
</div>

<script>
export default {
  data() {
    return { /* Your other data */ };
  },
  methods: {
    hasTooltip(item) {
      return Object.keys(item.label.attrs).includes('tooltip');
    }
  },
};
</script>

3. Update Documentation Comments: It would help improve maintainability to add more documentation comments explaining specific parts of the code (e.g., why certain conditions are checked).

4. Potential Bug: Ensure that the required attribute is correctly used with HTML attributes; it seems like a typo (class="color-danger" instead of aria-required). Adjust this if necessary.

These optimizations make the code cleaner and potentially enhance performance by reducing repetitive logic.
