Input.cart.line_items.each do |line_item|
  if line_item.line_price_changed? == false
    product = line_item.variant.product
    if line_item.properties.has_key?("_item_type")
      mainGroupID="";
      if line_item.properties["_item_type"] == "main"
        mainGroupID=line_item.properties["_group_id"]
        Input.cart.line_items.each do |line_item_inner|
           if line_item_inner.properties.has_key?("_item_type") and line_item_inner.properties["_item_type"]=="subitem"
            if line_item_inner.properties.has_key?("_group_id") and line_item_inner.properties["_group_id"]==mainGroupID
              line_item_inner.change_line_price(line_item_inner.line_price * 0, message: "")    
            end

Hello,

Maybe try to pull out the line items that you need rather than run through all. This is not tested so you might need to tweak

line_items = Input.cart.line_items.select {|li| li.properties["_item_type"] == "main" }

line_items.each do |line_item|

    next if line_item.line_price_changed?

    sub_items = Input.cart.line_items.select {|li| (li.properties["_item_type"] == "subitem") && (li.properties["_group_id"] == line_item.properties["_group_id"] ) }

    sub_items.each do |item| item.change_line_price(Money.zero, message: "") end
    

end

Output.cart = Input.cart
