I create a test project in order to test it on my end and I was able to observe the same behavior. This is why I have logged it in our feedback portal by creating a new feedback item on your behalf.

I have updated your Telerik Points.
To work around this, I can suggest setting the Padding property of the TitleElement and ScrollViewElement. Please refer to the following code snippet:
Random rand = new Random();
List<LineSeries> list = new List<LineSeries>();
for (var index = 1; index <= 35; index++)
LineSeries ls = new LineSeries();
ls.LegendTitle = "Series " + index;
for (int i = 1; i <= 100; i++)
foreach (LineSeries s in list)
s.DataPoints.Add(new CategoricalDataPoint(i, rand.Next(0, rand.Next(5, 20))));
this.radChartView1.ShowLegend = true;
this.radChartView1.LegendTitle = "Legend";
this.radChartView1.ChartElement.LegendPosition = LegendPosition.Right;
this.radChartView1.ChartElement.LegendElement.TitleElement.Padding = new Padding(0, 5, 0, 0);
this.radChartView1.ChartElement.LegendElement.ScrollViewElement.Padding = new Padding(0, 5, 0, 10);
As to the ExportToImage method, note that it creates an image file in the specified format from the current chart. So it is normal if you have scrollbars to appear in the exported image. The possible solution that I can suggest it to enlarge the form in a way all the legend items to be visible and the scrollbar doesn't show.
I hope this helps. Should you have further questions do not hesitate to ask.
