If you want me to get technical…
Just looking at the photos, there would not even be enough room along the front porch edge to adequately have room for a girder support, therefore I would say trusses. Of course a quick glance in the attic would verify.
Trusses would not require substantial bracing, but could require some type of support in this instance. Only reviewing home plans would provide insight. Again, not enough room so prolly OK. The support for the trusses in this instance are the exterior framed wall several feet in from the truss ends.
Lastly if the porch were a load supporting structure, ample beams or girders would also need to distribute load from the porch down, along the front of the deck. What is there doesn’t begin to provide any adequate support.
To answer the question, no its probably OK, but how was the deck itself built??
East TN is full of unskilled tradesman that were never forced to change their ways or improve on their own basic knowledge. Many just plain sucked, (many still do suck also) and didn’t bother to open a book to check framing spans before they started cutting.
To separate yourself as a good inspector you need to be able to evaluate these issues and properly document them in regards to their problems. The understanding of basic framing and load distribution are essential. We see so many types of construction, it’s not possible to understand it all. You sometimes have to make a judgement call, especially with very old homes. They will never meet modern building standards.
Lastly, if its bowing, it’s probably not done right.
