If this is a PDF you're building with iText, there's some small hope.  If
not, then... not so much.

I can think of a couple ways to create non-selectable text... though
creating them in iText will take some work.

1) Create a font with no/invalid character mapping.  For example: a font
subset using Identity-H encoding, and strip out the glyph-character tables
from the embedded font data.  That'd be tough and would require modifying
iText's font-handling code.

2) Draw the text as line art or a raster image.  The line-art version is
semi-doable in iText now using the PdfGraphic2D object... but inserting the
resulting PdfContent into a Document you're building will be a bit of a
chore.

If it's an existing PDF, you're pretty much screwed.  It's theoretically
possible, but Non-Trivial.
