北魏孝文帝即位时才5岁,由祖母冯太后临朝听政。冯太后进行一系列改革,推动了鲜卑族汉化,促进了民族交融。孝文帝受她的影响很大。冯太后去世后,他继续推行改革。

My 语感 is telling me the part in bold is not correct. Let's simplify the people, as it doesn't affect the grammar:
他受奶奶的影响很大。
It like it's trying to force "他受奶奶的影响" to be the subject of the sentence. I would instead expect something like:
他很受奶奶的影响。
他深受奶奶的影响。
奶奶对他的影响很大。
Question: Is 孝文帝受她的影响很大 grammatical, and if so, what is the underlying grammar structure?
Edit: Thinking about this a big more, it appears to be a 杂糅 grammar issue. Overlapping 他受奶奶的影响 with 奶奶的影响很大.
