Can do try/except if it fail with KeyError then append something else or can also pass out error so it continue.

>>> elbv1 = []
>>> try:
...     elbv1.append(d['responseElements']['loadBalancers'])
... except KeyError:
        # pass    
...     elbv1.append(d['responseElements'])
...     
>>> elbv1
[{'dNSName': 'my-loadbalancer-1234567890.elb.amazonaws.com'}]
