I don't find these names particularly clear - it is difficult to guess what l stands for without reading the documentation, and even with the (C) documentation, I'm not sure what the t is for. This issue proposes renaming lgamma to logAbsGamma to more accurately represent its functionality (while maintaining the C name in the documentation so that users looking for that name can find it), and renaming tgamma to gamma since it seems to just be the gamma function? (ditto comment about documenting old name)
Note that #18998 also impacts tgamma
