Unlikely. If the process abandons your site because it takes too long to get any data, it'll not associate the data it did get with the failure, just your site. The information about your competitor it did manage to read before giving up will still go in the training pile, and even if it doesn't the process would likely pick up the same information from elsewhere too.

The only affect tar-pitting might have is to reduce the chance of information unique to your site getting into the training pool, and that stops if other sites quote chunks of your work (much like avoiding github because you don't want your f/oss code going into their training models has no effect if someone else forks your work and pushes their variant to github).
