Contact the copyright owner and ask for the multitrack or stems.
If you have not even asked permission ("cleared" the samples) you can not publish your derived work without violating their rights.
Just saying, this way you're doomed to stay under the radar. If that's fine with you, then it's fine with me as well.
With software extractions: it depends on the material you throw at it, and what artifacts you find acceptable. Not my speciality really...

Spleeter is pretty decent if you're going to DIY. The concept of phase inversion can also be helpful. If you're really lucky you can find an instrumental version and invert the phase so that the instrumentals cancel each other out and you're left with the vocals but there is a lot of luck involved here.
You can also use it to get samples out of the way that are difficult for Spleeter to catch. HipHop snares for example are very difficult to get rid off, but you're in luck because a lot of people are using the same drum samples in HipHop/Pop songs so you might be able to find the exact snare used and invert just the snare.
Then you can clean it up by manually cutting, getting rid of the sub frequencies, getting rid of the side information if the vocal is in mono, getting rid of reverbs/delays using (multiband) gates, etc. iZotope RX9 also has some nice tools for vocal isolation.

It´s true that an instrumental version is great to have, but if that does not exist, there may be instrumental parts in the vocal version, which are similar to those with vocals, hence you could use the same approach.

Kn0ck0ut by St3pan0va can be used to isolate vocals, etc
https://www.kvraudio.com/product/kn0ck0ut-by-st3pan0vaKn0ck0ut takes two mono 44.1kHz inputs and spectrally subtracts one from the other. It can be used to help create 'acapellas' - to extract vocals from a track - if an instrumental version (or section) of the track is available.
