This is where output buffers come in handy, https://www.php.net/manual/en/book.outcontrol.php. I won’t repeat your entire code here, just the basics.

<?php 
  // only send output if there is content
  $has_content = false; // a flag to output content
  ob_start(); // start output buffering
?>
<p>this content will be buffered and only output if the repeater has values.</p>
<?php 
  if (have_rows('repeater field')) {
    while (have_rows('repeater field')) {
      the_row();
      if (get_sub_field('sub field name')) {
        // row has content
        // output the sub field
        the_sub_field('sub field name');
        // set flag to output content
        $has_content = true;
      }
    }
  }
  
  // get the content of the buffer and clear it
  $content = ob_get_clean();
  // if the flag was set then output the content
  if ($has_content) {
    echo $content;
  }
