How will I target the nearest child element aspect of on click area in vanilla JS?

how will i target nearest child element aspect of on click area in vanilla js means: i will click on outer side of li element and inner side of ul element and nearest li will be the target ..below Example Code..

Note: Jquery find method can not resolve the issue. I tried it, but it repeats the same element all time.

What I tried to achieve

From below picture red mark area: when I click on red mark area nearest li will be the target element. That is what I want... I did not resolve the issue. I think everything is possible ..there are so many selectors available in css & js...

Example Code

$(".amenities-filters-inner").each(function(i, el) {
  $(el).on("click", function(event) {
    event.preventDefault()
    var element = null;
    element = $(event.target).closest(".amenity_id");
    element = $(element).children().children().next();

    if ($(element).checked == true)
      $(element).checked = false;
    else {
      $(element).checked = true;
    }

    let dataId = null;
    if (element.hasClass('amenity_data')) {
      dataId = $(element).data('index');

    } else {
      element = $(event.target).find(".amenity_id");
      element = $(element).children().children().next();
      dataId = $(element).data('index');

    }

    console.log('$ el:' + element)
    console.log('$ index:' + dataId)
  })
});

document.querySelectorAll(".amenities-filters-inner ").forEach(function(item) {
  item.addEventListener("click", function(e) {
    e.preventDefault();

    let element = null;
    element = e.target.closest(".amenity_id");
    // element = e.target.querySelector(".amenity_id");
    element = element.children[0].children[1];
    element.checked == true ? element.checked = false : element.checked = true;

    let dataId = element.getAttribute('data-index');
    console.log('js el' + element)
    console.log('js index ' + dataId)
  })
})
