Something like:

Find set to use regular expressions with this in the Find field:
<title>[^<]+</title>

And Replace set to:
<title></title>

Then running ReplaceAll should do the trick. But I would make a Checkpoint (or save a copy) just in case it changes something unexpected.

Caveat: I have not tested that but somethin like that should do the trick.

AFAIR, an empty <title></title> will trigger an error in epubcheck.

Edit: Just checked using Sigil's empty EPUB3 and give the error:

OEBPS/Text/Section0001.xhtml, line 6,offset 158, Col: 10: ERROR(RSC-005): Error while parsing file: Element ""title"" must not be empty.
