Only if a series gets licensed by a foreign company, will it have subtitles. So, it won't have any subtitle when it airs in Japan.
So like the subtitles you see in Crunchyroll, Hidive, Netflix, funimation, Amazon, etc are official.
The subtitles present in almost all illegal streaming websites are fan made. They are commonly known as fan-subs.
The sad thing is these fan subs are mostly better than official ones.
