I am trying to add an order line to an existing sales order via XMLRPC
I am trying this:
r = api.execute_kw(db, uid, pwd, 'sale.order', 'write', [[sc]], { 'order_line': (0, '_', {'product_id': id, 'product_uom_qty': qty}) })
Where id, qty are integer numbers, and sc is the integer number with the ID of the sale order.
I get this error:

I see two mistakes here. One was already pointed at by Sanaullah Khan: A write on one2many or many2many fields has to be a list of "triplets".
And your call isn't correct. You're using args and kwargs on the call. The values parameter of write() is not a keyword argument/parameter. So get it into the args:
r = api.execute_kw(
db, uid, pwd, 'sale.order', 'write',
[[sc], {'order_line': \ # args
[(0, '_', {'product_id': id, 'product_uom_qty': qty})]}],
{}) # kwargs
