LSU's wins to date of note are:
Texas - Looked a lot better earlier in the year, now, not so much, and the points allowed is interesting.
Auburn - Close win, fewest points scored by LSU at 23-20.
Florida - Good win over solid team, but at home, 42-28.
Alabama - Great win on the road 46-41.'
A&M - TBD, let's assume a win of say 38-28, solid win over pretty good team.
The points allowed here is what makes OSU top dog at the moment, I think. OSU has very good looking wins over Cincy, Wisconsin, Penn State, all in C-bus, and nobody else has been close except perhaps MSU initially.
Your choices in description here are interesting to me. Due to my own allegiance, and my marriage, I play closer attention to UT and A&M, than any other schools, by a longshot.
Texas has certainly had a disappointing season compared to preseason expectations, but 4 of the losses are to good teams (LSU, Oklahoma, Baylor, ISU ranked by CFP as 2,7, 9, and 23). The loss to TCU was definitely a bad one, but Texas has also beaten 3 teams with winning records (#21 OkSate 8-3, Kansas State 7-4, and Louisiana Tech 8-3).
On the other hand, while the Aggies have a similarly long list of losses to good teams (Clemson, Alabama, Georgia, and Auburn ranked by CFP as 3,4,5,15) they haven't beaten a single team with a winning record.
So while I'm certainly disappointed in Texas' season, I'm not sure I'd describe a potential LSU win over the Ags as a "solid win over a pretty good team." Your hypothetical of an LSU 10-point win over a 7-5 A&M team doesn't look to me as being much different than a 7-point win over a 7-5 Texas team. And, since Texas actually has beaten 3 teams with winning records, while A&M has beaten 0 teams with winning records, I'm hard-pressed to describe that Aggie team as better than Texas. There are signs pointing to them being worse.
Now, if Ags actually beat LSU and win their first and only game against a team with a winning record, then I suppose I might have to re-evaluate my position.
