A receiver, either stereo or multichannel, is going to let you adjust the volume of any speakers connected to it. Almost all receivers these days come with remotes, so yes - you can control it with a remote.
With a receiver, you'd be using unpowered speakers because the receiver will power them. You could also hook up that TV to powered speakers (which would have audio inputs for the audio cable coming from the TV, a power cord, and a volume control of their own), such as powered "monitors" or a powered soundbar. Some powered speakers come with remotes and some don't.
