Here's what I'd suggest - it's very quick and is easier than removing the function altogether :)

First, she'd either want a child theme active or to use something like Simple Custom CSS so she can enter CSS and still be able to update. Then, she'd add the following:

.woocommerce .col2-set .col-2, .woocommerce-page .col2-set .col-2 {
    display: none;
}

That leaves this, which works but isn't pretty:

So to make it look nice and neat, we can add this instead:

.woocommerce .col2-set .col-2, .woocommerce-page .col2-set .col-2 {
    display: none;
}
.woocommerce .col2-set .col-1, .woocommerce-page .col2-set .col-1 {
    width: 100%;
}
p#billing_email_field {
    float: right;
}

Which should look nice in most situations.
