Is there any way of loading extra libraries within KtikZ with the \usepackage{} command, like in other LaTeX documents?
I could not find any documentation.
And, of course, a MWE in this case is not possible.

As a simple workaround you could calculate the coordinates with a bit of trigonometry, which can be put in a macro.
Note that with compat=1.11 or newer axis cs is the default coordinate system. If you have compat=1.10 or older you need to use (axis cs:\rtheta{1}{30}).
\documentclass[border=3mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.13}
\newcommand\rtheta[2]{{#1*cos(#2)},{#1*sin(#2)}}
\begin{document}
\begin{tikzpicture}
\begin{axis}[axis lines=middle,ymin=-1,ymax=1,xmin=-1,xmax=1]
\draw (\rtheta{0}{0}) -- (\rtheta{1}{30}) -- (\rtheta{1}{120});
\end{axis}
\end{tikzpicture}
\end{document}
Put shaded area on background layer:
\documentclass{standalone}
\usepackage{pgfplots}
\pgfdeclarelayer{background}% determine background layer
\pgfsetlayers{background,main}% order of layers
\begin{document}
\begin{tikzpicture}
\begin{loglogaxis}[domain=1:100,xmin=1,xmax=100,ymin=1,ymax=100,grid]
\begin{pgfonlayer}{background}
\fill[color=black!10] (axis cs:5,1) rectangle (axis cs:20,100);
\end{pgfonlayer}
\addplot[black] coordinates {(1,1) (5,10) (20,10) (100,100)};
\node at (axis cs:10,10) [above] {constant};
\end{loglogaxis}
\end{tikzpicture}
\end{document}

Click the
Editbutton and add any package you need to the template.Mine follows for reference:
The
<>mark is where the code you type in KtikZ will be placed.
