An LLM will probably be able to do most of what human minds can do like reason, predict, hypothesize, research, and even get hooked up to other systems to: Visualize, smell, taste, balance, and even direct the movement of limbs, but an LLM can't and won't ever be able to: Feel pain, bliss, anger, sadness, can't feel positive/negative, can't eat/drink, be hungry, feel fatigued, get excited, enjoy things, dislike things, contemplate, meditate, feel warm or cold (though it can detect it), can't feel dizzy (though it can know when it's off balance) - any action where having an experience is a necessary part of what it's doing and the output of it, an LLM is not sufficient to deliver on and never will be.

To compare to a brain, the LLM is like the prefrontal cortex or language and decision network in the outermost layer, but we would still need the amygdala in that metaphor - emotional drives, urges, episodic first-person memories, and experiential components that accompany the language and complete it with personhood.

For raw sensations and tactiles we might need that innermost brain stem - which is probably more chemistry than computation - for the "lights to be on". For example, some jobs will require not just language intelligence, and not just personhood, but for the light behind the images and feelings in the sensations, so that it feels (and would be) alive.
