Tolkien's books are just as full of witchcraft as Harry Potter is.

They aren't, so there's your answer. There are no LotR heroes using witchcraft. The abilities of Gandalf, Aragon, elves, etc. are racial and special traits (as in, owing to their species).

They do not practice magic, alchemy, etc.  They're more analogous to comic-book superheroes.

Richard Abanes, author of "Harry Potter and the Bible", warns: “Ultimately, only a short distance needs to be covered in order to cross over from Harry’s world into the realm of real occultism.”

An Example of Symbolic Analysis

How the ‘Deathday Party’ in Book 2 is, in fact,  a parody of the Holy Eucharist

On Halloween night, Nearly-headless Nick, the friendly ghost, invites Harry at his Deathday Party in a dungeon.  The whole place is dressed in black as in preparation for a black mass (black drapes, jet-black tapers, a thousand black candles, etc.).  It is indeed a parody of the Holy Mass, especially the table:

On the other side of the dungeon was a long table also covered in black velvet.  The smell was quite disgusting.  Large rotten fish were laid on handsome silver platters, cakes, burned charcoal black, were heaped on salvers; there was a great maggoty haggis, a slab of cheese covered in furry green mould and, in pride of place, an enormous grey cake in the shape of a tombstone, with tar-like icing forming the words Sir Nicholas de Mimsy-Porpington died 31st October, 1492.  Harry watched, amazed, as a portly ghost approached the table, crouched low and walked through it, his mouth held wide so that it passed through one of the stinking salmon.

-         ‘Can you taste it if you walk through it?’ Harry asked him.

-         ‘Almost,’ said the ghost sadly.

This table is an altar with a black velvet tablecloth, as in a Requiem Mass.  Here the fish, a symbol of Christ (IKTUS), is not only dead but rotten, exactly like God’s enemies wish Him to be (actually, there is a Greek group of Heavy Metal Rock that calls itself ‘Rotten Christ’!). The fish represented with bread traditionally refers to the Eucharist.  The “bread” here is the “cakes burned charcoal black”, like black Hosts used in a black mass.  The night of Halloween is believed to be the night where the veil is the thinnest between the worlds of the living and the dead, but this table shows the Living Christ as a dead and rotten fish with burned hosts (meaning that the Eucharist is dead food for brain dead people), while it exalts ghosts, who are believed to be dead but who are allegedly very much alive. The fish (i.e. the One it symbolizes) is lying flat, hopelessly horizontal whereas the wizard’s tombstone is erect, gloriously vertical “in pride of place”, like a promise of immortality.  

On the esoteric side, fish almost always means salmon in the Celtic tradition. Eating salmon is believed to give clairvoyance and omniscience. Moreover, the symbolism of salmon is the same as that of the wild boar, which is likened to the Druid because he lives alone in the forest and who is “the animal of sacred science”, i.e. divine knowledge, Gnosis.  The sadness of the ghost who tries to eat the salmon is not only that of the ghost who cannot eat anything anymore, but also the deep regret of the soul who is also deprived of the Gnostic sacred science.
