Well for starters the linebacker duo they have now - one wasn’t even on the initial 53 and the other was a late addition to the team in camp. Nakobe dean has underwhelmed when played but now is on injured reserve. Then by nature the eagles are typically aggressive when it comes to positional depth and Leonard would provide some security for the position.
There’s also Philly based places saying the same thing I am and hinting that at worst there will be interest as evidenced by the 2 links below….

“It is no secret that the Philadelphia Eagles have been a little thin at linebacker this season. The Birds lost T.J. Edwards to the Chicago Bears in free agency over the summer and, more recently, have had to put Nakobe Dean on the injured reserve with a Lisfranc injury. While Zach Cunningham and Nicholas Morrow have done an admirable job, they could always use a little backup”
The eagles were looking for linebackers at the trade deadline according to reports as well and have long term questions about the position so it only make sense to add depth and take a flyer on Leonard :

Another outlet that think they are a good fit ( it is bleacher report but it contains tweets that show linebacker interest at deadline )
