You do not need the true bearing to the station in order to navigate to it. However, if you don't have a GPS or other NAV equipment on board, you need some way to estimate your groundspeed, and knowing the true bearing can help you do that. Winds aloft forecasts are given with reference to true north, so if you know your own track relative to true north and ...

You don't get either and you don't need it.
The VOR signal gives you a radial to the station. This is normally referenced to magnetic north, because that's what you have on board¹, but it might have been last aligned twenty years ago and so might be a couple of degrees off as the magnetic declination slowly changes over time.
It does not matter what it is ...

The radials extending from the VOR are normally based on local magnetic variation (the compass rose around the VOR on the chart is angled off true by the amount of local variation so that the 360 deg Radial is pointing to the magnetic pole). The VOR gives no bearing information relative to the airplane; it only tells you that you are somewhere along, or to ...

The short answer is no, you don't need the true bearing to the station if you have magnetic bearing. Presuming of course that your airplane has a magnetic compass to fly that bearing, there is simply no reason to convert to true.
