node_title_list is deprecated

This is a procedural function in node.module that was previously used by statistics and forum modules. It is no longer used by Drupal core.

To replicate the functionality, you can do the following:

    $nodes = \Drupal::entityTypeManager()->getStorage('node')->loadMultiple($nids);

    $items = [];
    foreach ($nids as $nid) {
      $node = \Drupal::service('entity.repository')->getTranslationFromContext($nodes[$nid]);
      $item = $node->toLink()->toRenderable();
      $this->renderer->addCacheableDependency($item, $node);
      $items[] = $item;
    }

    return [
      '#theme' => 'item_list__node',
      '#items' => $items,
      '#title' => $title,
      '#cache' => [
        'tags' => \Drupal::entityTypeManager()->getDefinition('node')->getListCacheTags(),
      ],
    ];
