Is paying someone to fix LaTeX issues in one's thesis ethical? For my bachelor thesis in theoretical CS I paid someone to


fix some weird LaTeX issues I had
make some figures in LaTeX for which I provided exact (!) hand-drawn pictures
adjust the document class/template (font size, margins, ...) to university standards


In particular, all the text, formulae, figure sketches and remaining, say, 70% of the remaining typesetting were done by. Let me also say that I got the best grade possible to highlight that my contents were more than substantial for a bachelor thesis.

By academic standards, is it ethical to outsource parts of typesetting one's (BSc|MSc|PhD) thesis by paying someone?

Note that I am looking for opinions about the academic culture, not about legal situations. My university regulations are especially blurry and demand that one's thesis must be solely produced (in German: angefertigt) by the author. Whether that includes typesetting and in what proportion, is probably up to interpretation.

I do not see any unethical point in this. 
You were supposed to make an original contribution to your thesis in terms of your research. With respect to writing, you can take help from your friends, supervisor, or anyone else (free or paid). 

In our university in New Zealand, there was a dept. which used to charge a small fee to fix language issues for students with English as a second language. I suppose this should also work for the images/pictures thing as you are not an artist but an expert in your particular field.

Cutting it short, I do not see anything unethical in it.
