How to list products alphabetically in product category page

You can write a hook for that and add it to your functions file inside your child’s theme. Do not add this to your parent theme. If you are not using a child theme you should. I see your using Flatsome, so see if they have a child theme available to you.

add_action( 'woocommerce_product_query', 'custom_sort_products_alphabetically' );

function custom_sort_products_alphabetically( $query ) {
    if ( ! is_admin() && is_product_category() && $query->is_main_query() ) {
        $query->set( 'orderby', 'title' );
        $query->set( 'order', 'ASC' );
    }
}

Then add this snippet below anything in the functions.php file of your child theme.
