Tree to Ground Guying is possible but should be designed by a consulting structural engineer to minimize your liability.

First you should probably advise (in writing) the removal of the tree and acknowledge receipt of such advice. You might also get the homeowner to sign something to waive any of your responsibility should the tree fail.

Tree to Ground Anchor should weigh as much as the tree (engineer's CYA - you can guesstimate the weight - use Sherrill's chart). This involves drilling and filling a large hole with a great deal of concrete and steel. The cables would then be attached to the anchor.

From the pictures, you should use at least 3 anchors to do it right.

The cost could run as much as $2500 per anchor.

Picture attaches is an oak I did 2 years ago where 70% of the roots were severed on a live oak no one wanted to loose.
