Does "ssh -t" help?
YESS. It prevents the tty error from showing up and asks me for a password as expected. BUT, how do I then automate the entering of the password?
John Kennedy mentioned using expect which I've used before but found it to be 'finnicky'. I may have to look at it again...
Changing settings such as sudo configuration or ssh config may be daunting since I have a large number of systems(150+) that would need to be modified. :-/
