Is AngularJS an alternative?

When you are fetching city in item List , here just select Name,Zipcode,StateId,StateAbbreviation ,StateName. Then you don't need any loop. Just return the itemList as a Json Result.

You can try JQuery.each() function

JavaScript

var $ac = jQuery.noConflict();   
    $ac(document).ready(function () {
        debugger;
        $ac.ajax({
            url: '@Url.Action("GetAllCity", "Account")',
            type: "GET",
            success: function (data) {
                debugger;
                if (data != null) {
                 $ac.each(data, function(index, item) {
                    autocompletezipcodeBilling(item.MCZip);
                    autocompletezipcodeShipping(item.MCZip);
                    autocompleteCityBilling(item.MCCity);
                    autocompletezipCityShipping(item.MCCity);
                   });                 
                }
            }
        });
        });

I fear you ask the question the wrong way.
To assign large amount of data to array, it always involve a loop or many, hidden or explicit, not matter what, there is a loop.

I think the loop is not the root of the problem. You should rather explain us what you do with more details, so we can guess how to handle the problem.
The size of the data is an interesting detail.
