It is known that the instruction LegendFunction can be used to set the background color of the legend in a Plot or ListPlot, e.g.,

ListPlot[Range[0, 10], Joined -> True, 
 PlotLegends -> 
  Placed[PointLegend[{"Title"}, LegendFunction -> (Framed[#, Background -> White] &)], {Right, Top}]

Result of the plot

However, I haven't found a way to set the transparency (or opacity) of the background. If I don't specify any background color, then the legend is overlapped by the plots; if I set it to, say, white as in the example above, then the legend covers the curves I'm plotting. Is there anything in between?

    $\begingroup$ Change the background to Background -> Opacity[0, White] However, presumably the location of the legend was chosen to demonstrate whether the background was transparent rather than the final desired location. $\endgroup$

I suggest using Transparent directly as the most idiomatic short alternative, but you can also use Opacity as suggested by @BobHanlon in the comments.

    Range[0, 10]
    , Joined -> True
    , PlotTheme->"Scientific"
    , PlotLegends -> Placed[
            , LegendFunction -> (Framed[#, Background -> Transparent] &)
        , {Right, Top}
