I have had broken tie rods twice in the past 12 years, and only noticed when I went to do routine greasing. So, up to you, but I would be happy to drive it like that. I doubt whether you will find that anything else is damaged. It took me about 30 minutes to replace the rod and rebalance the tensions. Easy job.
I agree I had a broken tie rod over 20 years ago, went to the hardware store bought an appropriate length of screw rod, nuts and washers cut to required length put in place and tightened the nuts. Still going strong with over 50,000 miles driven and no issues, easy job to do yourself for a small outlay.
