A leaking strut is either no longer functioning or will stop functioning soon. It is a safety and handling issue. Struts should be replaced by pairs and at 110K miles the best bet would be to do new struts and/or shocks on all 4 wheels.
If money is the issue, you can stretch this but don’t go for a track day at your local racetrack. Keep you speeds below posted limits and keep an eye on tires for uneven wear. The struts job is to keep the tire on the road, especially in corners, and when stopping on uneven pavement. Your car will not performing up to specs so don’t push it too hard until you can afford a fix.
