[מִתְאַנֶּה is] an expression of “false accusation [=עֲלִילוֹת דְּבָרִים].”6Devarim 22:14.
Rabbeinu Bahya
על דבר הכסף השב באמתחותינו, “on account of the money he had put back into our feeding bags.” They reasoned that it certainly was not the norm that the people who came to Egypt to buy grain would all be entertained overnight at the palace of the ruler. They would find their lodgings in different parts of the city, at various inns, etc. They assumed therefore that Joseph’s gesture in inviting them served only as an excuse to attack them. They were afraid of a trumped up charge, and this is also the way Onkelos translates the words ולהתנפל עלינו not as a physical assault but as עלילת דברים, “false accusations.”
Ramban
AND TO FALL UPON US. I.e., as a man who intentionally throws his full stature upon his fellow.
Now Onkelos translated l’hithgoleil as meaning “to play the lord over us,” meaning that he will elevate himself above us, as the sea raises its waves.189See Ezekiel 26:3. Onkelos rendered the expression, and to fall upon us, as le’istakapha, meaning “to accuse us of things which did not occur,” since things which did not occur are expressed by the Hebrew word nopheil (falling), just as it says, Not one thing failed (‘naphal’).190Joshua 23:14. Similarly did Onkelos translate Wanton charges (‘aliloth d’varim’)191Deuteronomy 22:14. as taskophei milin (intrigues). Jonathan too translated to’einah192Judges 14:4. (pretext) as thuskapha.

Rashi
להתגלל means THAT THERE MAY BE ROLLED UPON US an accusation regarding the money AND THAT THIS MAY FALL UPON US. And according to Onkelos who rendered ולהתנפל עלינו by ולאסתקפא עלנא, it signifies seeking an occasion — just as we render in the Targum the words (Deuteronomy 12:17) עלילת דברים, which mean a pretext, by תסקופי מלין “intrigues” — but he did not translate it literally. The word ולהתגלל which he translated by לאתרברבא “to play the lord over us” he takes as connected in meaning with (Ecclesiastes 12:6) “the bowl of (גלת) gold”, and (Nahum 2:8) “And Huzzab the queen (גלתה) is carried away”, where these words from the root גלל denote symbolically royal rank.
